Elbow, Wrist & Hand Pain: Tennis Elbow, Carpal Tunnel & More

Arm pain diagnosis can be exceedingly easy or frustratingly difficult — the elbow, wrist, and hand are crowded neighborhoods of tendons, nerves, and small joints, and several very different problems produce similar complaints. The location of the pain and the movements that provoke it are the keys, which is why this guide includes self-tests you can try right at your desk. (A positive self-test means "worth getting examined," not a diagnosis — and remember that elbow pain can even originate in the neck, shoulder, or, rarely, the heart.)

Elbow pain

The elbow is most often injured by trauma — a single event like a sports injury, or accumulated damage from repeating the same motion thousands of times. History and examination point the way; a nerve conduction test, X-ray, or MRI sometimes seals the diagnosis.

Pain on the outside of the elbow

Tennis elbow (lateral epicondylitis) is tenderness right on the outer elbow bone, caused by small tears where the forearm muscles attach. Despite the name, most sufferers have never held a racquet — typists, writers, carpenters, and bricklayers get it too. Two desk self-tests: press your palms together as if praying, then push the good hand against the bad to bend the wrist backward; next, with the back of the bad hand against resistance and fingers pointing down, push outward. Pain on the outer elbow with either suggests the diagnosis. Treatment starts simple — rest from the offending activity, ice, heat, and massage — and escalates as needed to anti-inflammatories, a counterforce band worn a couple of inches below the elbow, a properly placed cortisone injection, and only rarely surgery.

Resistant "tennis elbow" that won't respond should make the doctor consider a trapped nerve instead. In radial tunnel syndrome, the pain sits more in the muscle just below the outer elbow than on the bone, and is often worse at night. In posterior interosseous syndrome, a branch of the radial nerve is pinched — the giveaway is weakness lifting the thumb and fingers, so the "thumbs-up" sign becomes difficult. Nerve entrapments need different treatment than tendon injuries, which is exactly why persistent "tennis elbow" deserves a specialist's exam.

Pain on the inside of the elbow

Golfer's elbow (medial epicondylitis) mirrors tennis elbow on the inner bone. Self-test: hook your palm under a desk ledge with the elbow bent and try to lift. Treatment is the same playbook as tennis elbow.

Ulnar nerve entrapment (cubital tunnel syndrome). The ulnar nerve — your "funny bone" — can be compressed in its tunnel just past the inner elbow, or by prolonged pressure. It powers the small muscles of the hand and gives feeling to the ring and little fingers, so injury shows up as weak pinch and grip, difficulty spreading the fingers, numbness in the pinky and ring finger, and the classic little annoyance of the pinky catching on your pocket. Similar symptoms can come from a pinched nerve higher up — in the brachial plexus or neck — so a good exam rules those out before blaming the elbow.

Median nerve entrapments near the elbow are less common but well described: pronator syndrome (the nerve caught under a forearm muscle, causing forearm tenderness, clumsiness, and hand weakness) and anterior interosseous syndrome, whose signature is the inability to bend the thumb tip — the "OK" sign collapses into a triangle instead of an O.

Wrist and hand pain

The wrist is a complex union of joints with eight small bones layered between forearm and hand. As at the elbow, pain comes chiefly from fractures, inflammation, or nerve entrapment.

Tendinitis and tenosynovitis. The tendons crossing the wrist ride inside slippery lubricated sheaths; repetitive strain inflames the sheath, causing pain when the tendon is touched or used, and — if neglected — scarring (stenosing tenosynovitis). De Quervain's disease is the thumb-side version: the self-test (Finkelstein's) is to tuck the thumb inside a fist and tilt the wrist away from the body, which stretches the inflamed tendon and reproduces the pain. A cortisone injection along the tendon sheath is often remarkably effective.

Carpal tunnel syndrome — the most famous nerve entrapment. The median nerve shares a tight fibrous tunnel at the wrist with nine tendons; repetitive wrist bending (keyboards, knitting, cycling) inflames the contents and squeezes the nerve. It's three times more common in women, usually appears in middle age, and follows a telltale pattern: pins-and-needles numbness in the thumb and first fingers, worse at night, relieved by shaking the hands out. Sufferers often drop things before they notice true weakness, and pain can travel up the arm, fooling doctors into hunting for a neck problem. (Occasionally both exist — "double crush syndrome.") Self-tests: hold the wrists fully bent for 30–60 seconds (Phalen's), or tap over the wrist crease (Tinel's) — reproduction of the tingling is a positive. Treat early: activity modification, a night splint, anti-inflammatories, and a steroid injection (limit two) that gives good relief for weeks to months in about half of patients. If numbness is becoming constant, don't wait — established nerve damage recovers poorly, and surgical release is straightforward and effective.

Guyon's canal syndrome — the other wrist entrapment. While carpal tunnel gets all the press, the ulnar nerve has its own tight passage on the pinky side of the wrist. It's compressed by pressure on the palm's heel — long-distance cycling, screwdriver work, karate strikes, pounding a hubcap — and shows up as wrist pain with weakness spreading the fingers and numbness along the pinky side. Handlebar padding and habit changes fix many cases.

Overuse (cumulative trauma) syndrome. Job-related repetitive strain — especially with vibrating tools — can damage muscle, tendon, joint, and bursa through microtrauma, reduced blood flow, and inflammation. Treatment is comprehensive: modify the workstation and technique, rest and splint, anti-inflammatories, physical therapy, and honest attention to the workplace and life factors that influence recovery.

Chronic hand pain more broadly usually traces to arthritis, nerve entrapment, tendinitis, or a generalized nerve disorder such as diabetic neuropathy — each with distinct treatment, which is the point of getting a real diagnosis.
