The elbow joint is a complex and fundamental structure for performing almost all daily, work, and sports activities. Functioning as a biomechanical bridge between the shoulder and the hand, the elbow allows for lifting loads, throwing objects, writing, and performing movements of extreme precision. When discomfort or functional limitation occurs in this area, the impact on quality of life can be significant. Investigating the causes of elbow pain is the first fundamental step to understanding the origin of the problem, preventing chronicity, and setting up a truly effective therapeutic and rehabilitative path.

This article thoroughly analyzes the anatomy of the joint, the most frequent pathologies, diagnostic pathways, and the best treatment strategies based on current scientific evidence in physiotherapy and orthopedic fields.

Anatomy and Biomechanics of the Elbow

The elbow is a hinge joint between the upper arm and forearm that enables bending, straightening, and rotation movements, with pain typically arising from structures like bones, muscles, tendons, or ligaments. To fully understand the pathologies affecting this area, a brief anatomical overview is useful. The elbow is not a single joint, but a complex formed by three main bones:

For a complete overview, see the comprehensive guide to elbow pain.

• Humerus: the arm bone.
• Radius and Ulna: the two forearm bones.

These bones meet to form three distinct joints enclosed within a single joint capsule:

• Humeroulnar joint: allows for flexion and extension movements (like a hinge).
• Humeroradial joint: participates in flexion/extension and rotation.
• Proximal radioulnar joint: fundamental for pronation and supination movements (rotating the palm of the hand upwards or downwards).

Stability is guaranteed by a robust system of ligaments (medial collateral and lateral collateral). Furthermore, the elbow is the anchoring point for numerous tendons: the tendons of the flexor muscles insert onto the medial epicondyle (inner part), while those of the extensor muscles insert onto the lateral epicondyle (outer part). Finally, three main nerves cross this region: the ulnar nerve, the median nerve, and the radial nerve. An alteration affecting any of these structures can generate pain.

Causes of Elbow Pain: The Most Common Pathologies

The causes of elbow pain are numerous and can result from functional overload, acute trauma, degenerative processes, or nerve compressions. The most frequent clinical conditions are analyzed below.

Lateral Epicondylitis (Tennis Elbow)

Epicondylitis is undoubtedly the most common cause of elbow pain. Despite the name “tennis elbow,” only a small percentage of patients suffering from it play this sport. It is a tendinopathy (often a tendinosis, meaning a degenerative process of the tendon tissue without a strong acute inflammatory component) that affects the insertion of the wrist and finger extensor muscles onto the lateral epicondyle of the humerus.
It is caused by repetitive movements of the wrist and hand, typical of manual labor (masons, plumbers, carpenters), prolonged use of a mouse and keyboard, or racket sports. The pain is localized on the outer part of the elbow and radiates along the forearm, worsening when gripping an object, turning a doorknob, or lifting a weight with the palm facing downwards.

Medial Epicondylitis (Golfer’s Elbow)

Medial epicondylitis, or golfer’s elbow, is the equivalent of lateral epicondylitis but affects the inner part of the elbow. The pathology involves the tendons of the wrist flexor and forearm pronator muscles, which insert onto the medial epicondyle.
In this case too, repetitive overload is the main culprit. It is common in golfers, throwers (baseball, javelin), weightlifters, and workers who perform repeated wrist flexion against resistance. The pain is felt in the medial region of the elbow and is accentuated by flexing the wrist against resistance or clenching the fist.

Olecranon Bursitis

The olecranon bursa is a small sac filled with synovial fluid located between the bony tip of the elbow (olecranon) and the skin. Its function is to reduce friction. Following direct trauma (a fall on the elbow), repeated microtrauma (constantly leaning on the elbows, a condition known as “student’s elbow”), or systemic pathologies (gout, rheumatoid arthritis), this bursa can become inflamed and fill with fluid.
The most evident symptom is a noticeable and localized swelling on the tip of the elbow, similar to a golf ball, accompanied by pain on pressure and, sometimes, warmth and redness.

Cubital Tunnel Syndrome (Ulnar Nerve Compression)

The ulnar nerve runs in a bony groove located on the inner part of the elbow (the cubital tunnel). Since the nerve is very superficial at this point (it is responsible for the “shock” felt when the elbow is inadvertently hit), it is easily subject to compression or stretching.
Keeping the elbow flexed for long periods (e.g., during sleep or on the phone) or resting it on hard surfaces can irritate the nerve. Symptoms are not limited to elbow pain but include tingling, numbness, and altered sensation radiating to the ring and little fingers of the hand. In severe cases, a loss of grip strength may occur.

Elbow Osteoarthritis

Although less frequent than knee or hip osteoarthritis, elbow osteoarthritis can develop due to wear and tear of the articular cartilage. It is often secondary to previous trauma (fractures or dislocations that occurred years before) or heavy labor sustained for decades. Symptoms include dull pain, joint stiffness (especially in the morning), joint crepitus during movement, and a progressive limitation in fully extending or flexing the arm.

Trauma, Fractures, and Dislocations

Acute traumatic events, such as falls with an outstretched arm or direct impacts during sports activities or accidents, can cause fractures (frequent ones include the radial head or olecranon) or dislocations (loss of joint relationships between the bones). These conditions generate acute, sudden, and sharp pain, accompanied by immediate swelling, visible deformity, and inability to move the joint. They require urgent medical intervention.

Biceps or Triceps Tendinopathy

The tendons of the biceps muscle (in the front of the arm) and triceps muscle (in the back) insert near the elbow. Sudden efforts or chronic overloads (such as weightlifting in the gym) can inflame or, in more severe cases, injure these tendons. The pain is localized respectively in the anterior crease of the elbow or just above the posterior tip.

Pain Radiating from the Cervical Spine

Pain perceived in the elbow does not always originate in the elbow itself. A problem at the cervical spine level, such as a herniated disc or osteoarthritis compressing nerve roots (particularly C5, C6, or C7), can generate radiating pain that travels down the arm to the elbow and hand (radiculopathy). In these cases, elbow pain is often accompanied by neck pain and neurological symptoms.

Symptoms Associated with Elbow Pain

Pain rarely presents alone. Depending on the underlying cause, it may be accompanied by a series of signs and symptoms that help frame the pathology:

• Joint stiffness: difficulty fully bending or straightening the arm.
• Swelling and edema: localized (as in bursitis) or diffuse (after trauma).
• Muscle weakness: difficulty gripping the hand, lifting light objects (like a water bottle), or opening jars.
• Paresthesias: tingling, altered sensation, or burning sensation (typical of nerve compressions).
• Joint crepitus: noises similar to “clicks” or a gritty sensation during movement.

Diagnosis: How to Identify the Problem

An accurate diagnosis is essential for successful treatment. It is always recommended to consult your doctor or physical therapist for a complete clinical evaluation.

The diagnostic process begins with a careful anamnesis (medical history): the professional will investigate work and sports habits, the mode of pain onset (acute or gradual), and the movements that exacerbate it.
Subsequently, the physical examination proceeds:

• Palpation: to identify the exact points of tenderness (e.g., epicondyle or medial epicondyle).
• Mobility tests: to evaluate active and passive joint range of motion.
• Specific orthopedic tests: such as Cozen’s Test or Mill’s Test for epicondylitis, or Tinel’s Sign for ulnar nerve involvement.

If clinical evaluation suggests it, the doctor may prescribe instrumental examinations:

• Ultrasound: first-line examination, excellent for evaluating the condition of tendons (thickening, micro-lesions, calcifications), ligaments, and the presence of effusions or bursitis.
• X-ray (RX): fundamental for excluding fractures, dislocations, or for evaluating the degree of osteoarthritis and the presence of bone spurs.
• Magnetic Resonance Imaging (MRI): used for a detailed analysis of soft tissues, complex ligamentous lesions, or cartilage pathologies.
• Electromyography (EMG): indispensable for confirming and quantifying the degree of nerve compression (e.g., cubital tunnel syndrome).

Physiotherapy Treatment and Rehabilitation

The treatment of elbow pain varies significantly based on the diagnosed pathology. However, the conservative (non-surgical) approach based on physiotherapy represents the gold standard for the vast majority of conditions, particularly for tendinopathies.

Acute Phase: Pain and Inflammation Management

In the very early stages of acute pain, the goal is to reduce symptoms. The principle of relative rest is often applied: not total immobilization, but temporary suspension of activities that trigger pain. The application of ice (cryotherapy) can be useful for managing acute pain and swelling. The doctor may prescribe non-steroidal anti-inflammatory drugs (NSAIDs) for a short period. In some cases, the use of specific braces (such as an epicondylitis brace) can relieve tension on the tendons during daily activities.

Instrumental Physical Therapies

Modern physiotherapy utilizes advanced technologies to stimulate tissue repair and control pain:

• Focused or Radial Shockwave Therapy: represents one of the therapies with the strongest scientific evidence for the treatment of chronic tendinopathies (lateral and medial epicondylitis). They stimulate neoangiogenesis (formation of new blood vessels) and regenerative processes of the tendon.
• High-Power Laser Therapy (Nd:YAG): excellent for its anti-inflammatory and deep biostimulating effect.
• Tecar Therapy: useful for improving local vascularization, reducing associated muscle contractures, and draining any edema.

Manual Therapy

The physical therapist’s manual intervention is crucial. It includes:

• Joint mobilizations: to restore the correct mechanics of the elbow, wrist, and, if necessary, the shoulder and cervical spine.
• Trigger point treatment and deep transverse friction massage (Cyriax): to relax the forearm musculature and treat fascial adhesions.
• Neurodynamics: nerve gliding and tensioning techniques (particularly for the ulnar and radial nerves) to free them from any entrapments and improve their mobility relative to surrounding tissues.

Therapeutic Exercise: The Heart of Rehabilitation

Scientific evidence shows that absolute rest is detrimental to tendons. Tendon tissue needs mechanical load to regenerate and strengthen. The physical therapist will set up a progressive exercise program:

• Isometric Exercises: muscle contractions without joint movement, excellent for reducing pain in the initial phase.
• Eccentric Exercises: the muscle contracts while lengthening. They are considered the treatment of choice for remodeling tendon structure in epicondylitis.
• Concentric and Plyometric Exercises: introduced in the final phases to regain maximal strength and prepare the joint for return to sport or heavy work.

Useful Exercises for Elbow Pain

Please note: The performance of any exercise must be pre-approved by your doctor or physical therapist to avoid worsening of the condition.

Below are some examples of exercises commonly integrated into rehabilitation protocols for elbow tendinopathies:

• Extensor stretch (for lateral epicondylitis): Extend the arm forward with the elbow straight. With the opposite hand, flex the wrist downwards so that the fingers point towards the floor. Maintain the tension (without acute pain) for 30 seconds. Repeat 3 times.
• Flexor stretch (for medial epicondylitis): Extend the arm forward with the palm facing upwards. With the opposite hand, gently pull the fingers downwards and towards the body. Hold for 30 seconds, 3 repetitions.
• Eccentric exercise for lateral epicondylitis: Sitting, rest the forearm on a table, leaving the hand off the edge, palm facing downwards. Hold a small weight (1-2 kg). Use the healthy hand to lift the weight (wrist extension). Release the healthy hand and slowly lower the weight (in 3-4 seconds) using only the injured hand. Repeat for 3 sets of 10-15 repetitions.
• Grip strengthening: Squeeze a soft rubber ball or a rolled-up towel for 5 seconds, then release. Repeat 15 times.

Prevention: How to Protect the Joint

Preventing the onset or recurrence of elbow pain requires attention to ergonomics and load management:

• Work ergonomics: Those who work at a computer should ensure their workstation is correctly configured. Forearms should be rested on the desk or armrests, maintaining an elbow angle of approximately 90 degrees. The use of ergonomic mice and keyboards can reduce stress on the tendons.
• Sports technique: In racket sports or golf, incorrect technique (e.g., a tennis backhand executed only with the wrist instead of the whole body) transfers enormous loads to the elbow. Relying on a coach to correct the athletic gesture is fundamental.
• Appropriate equipment: Use rackets with the right grip, correct string tension, and materials that absorb vibrations.
• Load management: Avoid sudden increases in the intensity or volume of training or manual work. The body needs gradual adaptation to efforts.
• Warm-up: Always perform warm-up exercises for the arms and wrists before intense activities.

Frequently Asked Questions (FAQ)

How long does it take to recover from epicondylitis?

Recovery times for epicondylitis (or medial epicondylitis) vary significantly based on the severity of the condition and the timeliness of intervention. If treated in the early stages, it can resolve in 4-6 weeks. However, if the condition is chronic and there is advanced tendon degeneration (tendinosis), full recovery can take from 3 to 6 months, or in some cases up to a year, following a consistent rehabilitation program.

Is ice always useful for elbow pain?

Ice (cryotherapy) is very useful in acute phases, immediately after trauma or when there is strong inflammation with swelling and warmth (e.g., acute bursitis or an exacerbation of tendinitis). However, in chronic tendinopathies (where inflammation is absent and tissue degeneration prevails), prolonged use of ice could slow down healing processes by reducing blood flow. In these cases, therapies that stimulate vascularization are more indicated.

Can I continue training if I have elbow pain?

Continuing to train “through the pain” is strongly discouraged, especially if the pain is acute or worsens during or after activity. This behavior can transform a mild inflammation into a chronic pathology or a tendon injury. It is advisable to modify training, eliminating exercises that cause pain and focusing on other muscle groups, while awaiting evaluation by a healthcare professional.

When is surgery necessary for the elbow?

Surgical intervention is considered a last resort. It is only considered after well-conducted conservative treatment (physiotherapy, physical therapies, possible medical infiltrative therapy) has failed for a period of at least 6-12 months, and the pain is debilitating for daily life. Exceptions include severe acute trauma, such as displaced fractures or severe dislocations, or nerve compression syndromes with severe motor deficit, which may require surgical intervention promptly.

Is the use of a brace or strap recommended?

The use of a brace (such as a counterforce brace for epicondylitis) can be very useful for managing symptoms during work or sports activities that cannot be suspended. The brace acts by modifying the tendon’s traction point, relieving the painful bony insertion. However, the brace does not “cure” the pathology: it should always be considered a temporary aid to be combined with a rehabilitation and therapeutic exercise program.
