Two Sides of the Same Coin
Tennis Elbow (Lateral)
Pain on the outside of the elbow
Affects the tendons that extend the wrist and fingers
Worse gripping, lifting, or twisting
Golfer's Elbow (Medial)
Pain on the inside of the elbow
Affects the tendons that flex the wrist and fingers
Worse gripping or flexing the wrist
What Contributes to It
Repetitive gripping or wrist motion — tools, typing, racquet sports, golf, weightlifting
A sudden increase in activity or a new repetitive task
Forearm weakness
Most common after age 40, regardless of whether you play the namesake sport
How We Treat It
Calm the irritation — activity modification, and a counterforce brace can offload the tendon.
Progressive tendon loading — isometric holds, building into strengthening; this is what actually rebuilds tendon capacity.
Address grip mechanics — grip size, technique, and equipment adjustments where relevant.
Return to activity gradually — matching load to what the tendon can tolerate.
Bottom line: Both conditions respond well to a progressive loading program. Recovery can take a few months, but the large majority of people improve substantially without injections or surgery.
