Detailed view of elbow anatomy and examination

Anatomy Overview

Understanding Your Elbow

The elbow joint is where three bones meet: the humerus (upper arm), radius, and ulna (forearm). It functions as both a hinge joint for bending and a pivot joint for forearm rotation, making it essential for virtually every hand and arm activity.

The elbow handles significant forces during gripping and lifting, and its relatively exposed position makes it susceptible to overuse injuries, nerve compression, and direct trauma.

Bones: Humerus, radius, ulna, radial head, olecranon
Epicondyles: Lateral (outer) and medial (inner) bony bumps, tendon attachment points
Nerves: Ulnar nerve (funny bone), radial nerve, median nerve
Ligaments & Bursae: Annular ligament, collateral ligaments, olecranon bursa

Common Conditions

What Causes Elbow Pain?

Elbow pain most often results from overuse injuries affecting the tendons, but nerve compression, bursitis, arthritis, and fractures are also common causes.

Tennis Elbow (Lateral Epicondylitis)

Pain on the outer elbow from overuse of forearm extensors. Despite the name, most cases occur from repetitive work activities, not tennis. Affects 1-3% of adults.

Most Common

Golfer’s Elbow (Medial Epicondylitis)

Pain on the inner elbow affecting the flexor tendons. Less common than tennis elbow. Caused by gripping, throwing, or repetitive wrist flexion activities.

Inner elbow

Cubital Tunnel Syndrome

Ulnar nerve compression at the elbow. Causes numbness and tingling in the ring and pinky fingers. Worsens when elbow is bent during sleep or phone use.

Nerve compression

Olecranon Bursitis

Swelling over the point of the elbow from inflammation of the bursa. Often from leaning on elbows or direct trauma. Creates a visible swelling at the elbow tip.

Swelling at tip

Elbow Arthritis

Less common than hip or knee osteoarthritis, but can occur after injuries or in rheumatoid arthritis. Causes stiffness, grinding, and loss of range of motion.

Degenerative

Radial Head Fracture

Usually from a fall on an outstretched hand. Causes immediate pain, swelling, and difficulty rotating the forearm. Requires prompt medical evaluation.

Symptom Guide

Symptoms & Pain Location

Where you feel elbow pain provides important clues about the underlying cause. Use this guide to identify your symptoms.

Outer Elbow (Lateral)

Tennis elbow pain at the lateral epicondyle. Worsens with gripping, turning a doorknob, or lifting with palm facing down. May radiate down the forearm.

Inner Elbow (Medial)

Golfer’s elbow at the medial epicondyle. Pain with gripping, throwing, or wrist flexion. May cause weakness in hand and wrist grip strength.

Back of Elbow (Posterior)

Olecranon bursitis causes visible swelling at the elbow tip. Triceps tendinitis causes pain with straightening the arm against resistance.

Radiating to Forearm & Hand

Cubital tunnel syndrome causes numbness and tingling in ring and pinky fingers. Radial tunnel syndrome causes deep aching in the outer forearm.

Seek Immediate Medical Attention

Visible deformity of the elbow joint after a fall or injury
Inability to bend, straighten, or rotate the forearm
Severe pain and swelling following trauma, especially from a fall on outstretched hand
Fever combined with elbow swelling, redness, and warmth (possible joint infection)
Sudden loss of grip strength or inability to carry objects

Getting Diagnosed

How Elbow Pain Is Diagnosed

A proper diagnosis combines physical examination with specific provocation tests. Your doctor will assess tenderness, strength, and nerve function to identify the source of your pain.

Physical Examination

Palpation of epicondyles, provocative tests (Cozen’s test, Tinel’s sign), grip strength assessment

Medical History

Occupational activities, sports involvement, onset pattern, previous injuries or surgeries

Imaging Studies

X-rays for fractures and arthritis; MRI for tendon tears; ultrasound for tendinopathy evaluation

Nerve Conduction Studies

Electromyography (EMG) to assess ulnar nerve function in suspected cubital tunnel syndrome

Treatment Options

How to Treat Elbow Pain

Most elbow conditions respond well to conservative treatment, with 80-95% of tennis elbow cases resolving without surgery. A stepwise approach is recommended.

Conservative Treatments

Avoid or modify the aggravating activities. For tennis elbow, this means reducing repetitive gripping and wrist extension. Apply ice for 15-20 minutes several times daily during acute pain. Use ergonomic tool modifications at work.

Best for: Acute flare-ups, early-stage tendinopathy

Eccentric strengthening exercises are the cornerstone of treatment for lateral and medial epicondylitis. A physical therapist guides progressive loading of the affected tendons, promoting healing and preventing recurrence. The Tyler Twist with a FlexBar is a well-studied home exercise.

Best for: Tennis elbow, golfer’s elbow, chronic tendinopathy

Effectiveness:

Very High

A counterforce brace (forearm strap) worn just below the elbow reduces stress on the affected tendon during activities. Oral or topical NSAIDs provide short-term pain relief and reduce inflammation. Use NSAIDs as directed and consult your doctor for long-term use.

Best for: Symptom management during recovery, return to activity

Adjusting workstation height, using ergonomic keyboard and mouse, and modifying grip technique on tools can significantly reduce tendon strain. Proper grip size on sports equipment (tennis rackets, golf clubs) is critical for athletes.

Best for: Work-related elbow pain, preventing recurrence

Medical Treatments

Provides short-term relief (2-6 weeks), but evidence suggests worse long-term outcomes compared to physiotherapy alone for tennis elbow. May weaken the tendon with repeated injections. Generally reserved for acute, severe pain.

Best for: Short-term relief of severe acute pain

Effectiveness:

Moderate (short-term)

PRP (Platelet-Rich Plasma): Injecting concentrated platelets from your own blood may promote tendon healing. Emerging evidence shows promise for chronic tennis elbow.

Extracorporeal Shockwave Therapy (ESWT): Non-invasive sound wave treatment that stimulates healing in chronic tendinopathy. Multiple sessions typically needed over several weeks.

Best for: Chronic cases that haven’t responded to conservative treatment

Surgical Options

Only 5-10% of tennis or golfer’s elbow cases require surgery after 6-12 months of failed conservative treatment. The procedure involves releasing or debriding the damaged portion of the tendon. Can be done open or arthroscopically with good outcomes.

Best for: Chronic epicondylitis unresponsive to 6-12 months of conservative care

Effectiveness:

High

For cubital tunnel syndrome that doesn’t respond to conservative measures (night splinting, activity modification). The ulnar nerve is moved from behind the elbow to a new position in front, relieving compression. Recovery takes 3-6 months for full nerve regeneration.

Best for: Severe or progressive cubital tunnel syndrome

Effectiveness:

High

Exercise Program

Exercises for Elbow Pain Relief

Strengthening the forearm muscles through eccentric exercises is the most effective way to treat and prevent tennis elbow and golfer’s elbow. These exercises promote tendon remodeling.

Always consult with a physical therapist or doctor before starting a new exercise program.

Extend your affected arm straight out in front of you, palm facing down.
Use your other hand to gently bend the wrist downward, fingers pointing toward the floor.
You should feel a stretch along the top of your forearm.
Hold for 30 seconds. Repeat 3 times, several times daily.

3 reps 30s hold Beginner

Keep your elbow fully straight during the stretch. Stop if you feel sharp pain.

Extend your affected arm out, palm facing up.
Use your other hand to gently bend the wrist downward so fingers point toward the floor.
You should feel a stretch along the inside of your forearm.
Hold for 30 seconds. Repeat 3 times, several times daily.

3 reps 30s hold Beginner

Sit with your forearm resting on your thigh or a table, holding a hammer or weighted object by the handle.
Slowly rotate your forearm so your palm faces down (pronation).
Slowly rotate back so your palm faces up (supination).
Repeat 15-20 times per set. Do 2-3 sets daily.

2-3 sets 15-20 reps Beginner

Rest your forearm on a table, wrist over the edge, palm facing down.
Hold a light weight (1-2 lbs). Use your other hand to help lift the wrist upward.
Slowly lower the weight over 3-5 seconds using only the affected arm (eccentric phase).
Use the other hand to return to the start position. Repeat 10-15 times, 3 sets daily.

3 sets 10-15 reps Intermediate

The eccentric (lowering) phase is key. For the Tyler Twist variation, use a TheraBand FlexBar for added resistance and proven effectiveness.

Hold a rolled-up towel lengthwise with both hands.
Wring the towel by twisting your hands in opposite directions, as if wringing out water.
Repeat 10 times in each direction.
Do 2-3 sets. Progress by using a thicker or wetter towel for more resistance.

2-3 sets 10 reps each way Beginner

Working with a Physical Therapist

A physical therapist can design a progressive exercise program tailored to your specific condition, monitor your technique, and advance your program as you improve.

For stubborn cases, manual therapy techniques like deep friction massage and joint mobilization may complement your exercise program and accelerate recovery.

Protect Your Joints

Preventing Elbow Pain

Proactive steps can significantly reduce your risk of elbow overuse injuries and help you stay pain-free long term.

Use Proper Grip Size

Whether on a tennis racket, golf club, or work tool, the correct grip size reduces strain on forearm tendons.

Avoid Repetitive Strain

Take regular breaks during repetitive tasks. Alternate hands when possible and use power tools to reduce manual gripping.

Strengthen Forearm Muscles

Regular forearm strengthening exercises build tendon resilience. Wrist curls, reverse wrist curls, and grip exercises help.

Use Braces or Straps for Sports

A counterforce brace during sports and manual work reduces tendon load and can prevent injury recurrence.

Warm Up Before Activity

Light stretching and warm-up exercises prepare tendons for activity and reduce injury risk during sports or manual work.

Maintain Good Technique

Proper form in sports and at work prevents overloading specific tendons. Consider coaching or ergonomic assessment.
