Tennis elbow vs. golfer's elbow: which one do you have?
Outer elbow or inner elbow — that one detail separates two different injuries with two different fixes. A quick, practical guide to telling them apart, and what each one needs to heal.
Elbow pain from gripping, lifting, or repetitive arm work almost always comes down to one question: is it on the outside of the elbow, or the inside? That single detail separates tennis elbow from golfer's elbow — two injuries that get lumped together constantly but load different tendons and need slightly different fixes.
Outer elbow or inner elbow — the one-question test
Pain on the outside of the elbow is tennis elbow — the clinical term is lateral epicondylitis. It involves the forearm extensor muscles, the ones that cock your wrist back and stabilize your grip, which all anchor to that bony bump on the outer elbow.
Pain on the inside of the elbow is golfer's elbow — medial epicondylitis. That's the forearm flexor group, the muscles that curl the wrist and power a clenched grip, anchoring to the inner bump.
How each one actually behaves
- Tennis elbow (outer). Hurts with wrist extension and grip — shaking hands, lifting a coffee cup, turning a doorknob, holding a drill. Grip often feels weak or unreliable. The full story is in our tennis elbow guide.
- Golfer's elbow (inner). Hurts with wrist flexion and a strong grip — pull-ups, carrying groceries, swinging a club or bat. Can send an ache down the inner forearm, and gripping hard may feel weak. We cover the golf-side version in our golf injuries article.
Despite the names, most cases involve no racquet and no clubs. Both are overuse tendinopathies — a tendon loaded harder or more often than it could adapt to — and desk work, lifting, and trades like plumbing or carpentry produce plenty of each. Cleveland Clinic puts tennis elbow's peak incidence in the 30–50 age range, racquet or not.
Same elbow, opposite sides, mirror-image injuries: tennis elbow is the muscles that lift your wrist, golfer's elbow is the muscles that curl it.
Can you have both at once?
Yes, though it's uncommon. Heavy grip-intensive work loads both tendon groups, so a laborer or climber can irritate both attachments. More often what looks like “both” is one true tendinopathy plus referred pain from the neck or shoulder — nerve irritation higher up can mimic elbow and forearm symptoms, which is one of the things we screen for. If your symptoms include tingling into the hand, our carpal tunnel guide explains how to tell nerve symptoms from tendon pain.
What actually helps either one heal
Tendons adapt to load — that's both the injury and the cure. Complete rest calms the pain but leaves the tendon weak, so it flares again the day you go back to normal life. The plan that works is graded: settle the irritation, then progressively re-load the tendon until it tolerates more than your daily demands.
At The Spine Studio that looks like Pin & Stretch soft-tissue work through the forearm, Corrective Exercise Programming to re-load the tendon step by step, and for stubborn chronic cases, Shockwave Therapy — which is specifically well-studied for tendinopathies like these.

Frequently asked questions
- What is the difference between tennis elbow and golfer's elbow?
- Tennis elbow (lateral epicondylitis) is pain on the outside of the elbow, where the forearm muscles that extend your wrist attach. Golfer's elbow (medial epicondylitis) is pain on the inside, where the muscles that flex your wrist and power your grip attach. Both are overuse tendon injuries — the side of the elbow tells you which tendon group is involved.
- Why does the inside or outside of my elbow hurt when I grip things?
- Gripping loads both forearm muscle groups, which anchor on opposite sides of the elbow. If gripping and lifting with your palm down hurts the outer elbow, that points to tennis elbow. If a strong clench or curling motion hurts the inner elbow, that points to golfer's elbow. Neither requires playing the sport it's named after — desk work, lifting, and trades cause most cases.
- Can you have tennis elbow and golfer's elbow at the same time?
- It's possible with heavy grip-intensive work, but it's uncommon. When both sides of the elbow hurt, it's often one true tendon problem plus referred pain from the neck or shoulder, since irritated nerves higher up can mimic elbow symptoms. That's worth a proper exam rather than guessing.
- How do you fix tennis elbow or golfer's elbow?
- Settle the irritation, then progressively re-load the tendon — tendons heal by adapting to gradually increasing load, not by total rest. Hands-on soft-tissue work through the forearm, a step-by-step loading program, and shockwave therapy for stubborn chronic cases are the core tools. Complete rest usually means the pain returns the week you go back to normal activity.
