Why Does My Elbow Hurt When I Make a Fist?

Pain with making a fist may stem from several factors. The most common cause is medial epicondylitis (also known as “golfer’s elbow”), which affects the tendons on the inner side of your elbow. This condition is typically due to receptive activities that activate this tendon-like lifting heavy objects, typing, or painting. Forearm muscle strain is another possible cause. The flexor muscles, which help you make a fist, extend from your fingers through your forearm to your elbow. When these muscles are overworked or strained, their attachment point at the elbow becomes tender and painful. The pain typically worsens when you grip objects or make a fist, as these movements directly stress the irritated area. Ulnar nerve entrapment can also cause elbow pain when making a fist. The ulnar nerve runs through a groove on the inner side of your elbow, and when it becomes compressed or irritated, it can cause pain, tingling, and numbness that may worsen with gripping motions. If the pain persists or worsens, you should see a doctor for proper evaluation and treatment.
