The inside of the elbow that barks when you grip a club, a wrench, or a barbell. It is a capacity problem in the flexor tendons — and capacity is trainable.
Medically reviewed by Dr. Carson Bailey, PT, DPT · August 2026
Golfer's elbow, known clinically as medial epicondylitis, is an overload tendinopathy of the flexor-pronator tendons on the inside of the elbow; a Finnish population study of 4,783 adults found it in 0.4% of people aged 30–64, about a third as often as tennis elbow. Progressive loading of the wrist flexors has the best track record — in 20 patients whose previous injections and therapy had failed, six weeks of a daily eccentric exercise cut DASH disability scores from 34.7 to 7.9. RISE Physical Therapy treats golfer's elbow one-on-one in 45-minute sessions in Boise and Nampa, Idaho, with no referral required.
Golfer's elbow is a degenerative overload injury of the common flexor tendon, where the muscles that bend your wrist and turn your palm down anchor to the bony knob on the inside of the elbow; the pronator teres and flexor carpi radialis take most of it.[2] Despite the "-itis" in medial epicondylitis, these tendons show little classic inflammation under the microscope — what they show is disorganized collagen, tissue asked for more than it could rebuild.
It is the quieter sibling of tennis elbow. Among 4,783 Finnish adults aged 30 to 64, definite medial epicondylitis appeared in 0.4% against 1.3% for lateral, peaking in the 45-to-54 age band with no meaningful difference between men and women.[1] Note the age — this is not primarily a young athlete's injury, though throwers get their own version from valgus stress.
Golfer's elbow shows up as pain and tenderness on the inside of the elbow that worsens with gripping and with anything that bends the wrist or rotates the palm down. It usually builds over weeks. Book an evaluation if you notice:
Two patterns change the plan. Numbness or tingling into the ring and little fingers points at the ulnar nerve behind the medial epicondyle, reported alongside this condition in anywhere from about one in five patients to more than half.[2] And pain that began with one hard throw, pull, or fall — especially with a sense of instability — needs the ulnar collateral ligament screened, not a tendon program.
Golfer's elbow comes from repeated forceful gripping and wrist flexion, and golf accounts for only a slice of cases. The Finnish population study found repetitive movement, forceful activity, smoking, and obesity each independently associated with medial epicondylitis — a profile describing trades and manual work more than weekend sport.[1] The histories we hear around the Treasure Valley are carpentry and mechanic work, irrigation and landscaping season, climbing gyms, and lifters who added pulling volume fast. The shape is always the same: demand rose faster than the tendon's capacity. That does not make the tendon fragile — the ramp was just steep.
Golfer's elbow often does improve with time, but the evidence suggests a cortisone shot changes how fast you get there rather than how well. In a randomized, double-blind trial of 60 elbows, patients injected with methylprednisolone had significantly less pain than the placebo group at six weeks — yet the groups were indistinguishable at three months and again at one year, leading the authors to conclude that steroid injection gives only short-term benefit, with both groups largely reflecting the natural course of the disorder.[3] Two caveats. "Resolves eventually" can mean a long time: patients entering one eccentric-exercise cohort had been symptomatic for a mean of 19 months.[4] And the ulnar nerve passes directly behind this injection site — one more reason to treat injection as a way to make rehab tolerable, not as the plan. The reassuring part: the large majority of cases, reported in the range of 90% and above, are managed without surgery.[2]
Eccentric loading of the wrist flexors is the best-supported active treatment for golfer's elbow, though its evidence base is smaller than tennis elbow's. The most quoted result: 20 patients with chronic medial epicondylosis who had already failed medication, injections, or physical therapy added one eccentric wrist flexor exercise — twisting a rubber bar with the good arm and slowly releasing the twist with the painful one, three sets of 15, twice daily — and improved DASH disability scores by 77%, from 34.7 to 7.9, in six weeks.[5] A separate series ran 20 consecutive adults, mean age 47 with symptoms for a mean of 19 months, through a three-month home eccentric program.[4]
The limitation, stated plainly: a 2026 systematic review concluded that eccentric exercise appears to reduce pain and improve function in medial epicondylitis — especially inside a multimodal program — but that the certainty of the evidence remains low and larger randomized trials are needed.[6] Small samples, few control groups. What that changes in practice is modest: loading still has the best evidence behind it, the mechanism matches what is known about tendon adaptation, and the downside is negligible. It does mean we measure progress rather than assume it.
Treating golfer's elbow at RISE means finding the true source of the medial elbow pain, then dosing tendon load precisely enough that it adapts without flaring. Every session is a full 45 minutes, one-on-one with the same Doctor of Physical Therapy — which is what makes adjusting that dose week to week possible.
Resisted wrist flexion and pronation, grip testing, ulnar nerve screening, and a valgus stress check tell us whether this is tendon, nerve, ligament, or neck.
Isometric holds for pain relief, hands-on work through the forearm, and specific load edits so daily gripping stops re-irritating the tendon.
Eccentric and heavy slow resistance work builds real capacity back into the flexor-pronator group, then we reintroduce the swing, the tools, or the bar.
