Lateral and Medial Epicondylitis (Tennis Elbow & Golfer’s Elbow)

What is the Epicondyle?
The epicondyles are bony bumps on the inside (medial) and outside (lateral) of the elbow where forearm tendons attach.
What is This Condition?
Lateral epicondylitis (tennis elbow): irritation of the tendons on the outside of the elbow, usually involving the extensor carpi radialis brevis tendon.
Medial epicondylitis (golfer’s elbow): irritation of the tendons on the inside of the elbow that flex the wrist and fingers.
What are the Symptoms?
Pain and tenderness on the inside or outside of the elbow
Pain that worsens with gripping, lifting, or twisting motions
Weak grip strength
Discomfort that may radiate down the forearm
What Causes It?
Repetitive wrist and forearm motions (tennis, golf, throwing, manual work, typing)
Overuse of the forearm muscles and tendons
Sometimes no clear cause — it may develop gradually over time
How is It Diagnosed?
Exam: pain with resisted wrist or finger movement
X-rays: usually normal, but may rule out arthritis
MRI or ultrasound: occasionally used if diagnosis is unclear
How is It Treated?
Non-surgical:
Rest and activity modification
Ice and NSAIDs for pain relief
Physical therapy to stretch and strengthen the forearm muscles
Bracing or straps to reduce strain on the tendon
Cortisone injections for persistent pain
Orthobiologics (such as PRP) in select cases
Surgical:
Rarely needed, but involves cleaning out or repairing the damaged tendon if symptoms don’t improve after 6–12 months of non-surgical care
