There are many conditions and injuries that can lead to pain in the elbow—the pain can range from mild discomfort to severe. If the tendons that are attached to the outer bone of the elbow (the lateral epicondyle) become injured, inflammation and tendonitis can occur. This is what is known as tennis elbow, or lateral epicondylitis. Performing activities that require repetitive forearm motion, such as playing tennis, washing windows, or using a manual screwdriver, can lead to tennis elbow. Typically, the pain is felt on the outside of the elbow and may occur in conjunction with redness, warmth, and inflammation. Fortunately, tennis elbow doesn’t impact range of motion, because it doesn’t affect the inner joint. If the tendons that attach to the inner elbow become inflamed, it is called golfer’s elbow, or medial epicondylitis. Just as in tennis elbow, golfer’s elbow gets its name from the activity that is likely to cause it. However, golfer’s elbow can come from any activity that requires repetitive motion that strains the tendon. Pain from golfer’s elbow is felt in the inside of the elbow, but range of motion isn’t affected. Treatment for both conditions involve ice, rest, anti-inflammatory medication, bracing, and rehabilitative exercises.
