Answer: B - Tennis elbow, also known as lateral epicondylitis, is a condition that is related to the bursa in the elbow joint. The condition is caused by overuse or repetitive motions of the forearm and wrist, which can lead to inflammation and pain at the lateral epicondyle (the bony bump on the outside of the elbow).
In tennis elbow, the common extensor tendon, which originates from the lateral epicondyle and inserts into the forearm bones, becomes strained and irritated. This strain can lead to inflammation in the bursa that lies between the tendon and the lateral epicondyle. The bursa helps to reduce friction between the tendon and the bone, but when it becomes inflamed, it can cause pain and tenderness in the elbow.
Treatment for tennis elbow typically involves rest and physical therapy to reduce inflammation and promote healing of the affected tissues. Anti-inflammatory medications, such as ibuprofen, may also be prescribed to help reduce pain and swelling. In some cases, a brace or strap may be worn to help support the affected arm and reduce stress on the tendon. In severe cases, surgery may be necessary to repair the damaged tendon or remove the inflamed bursa.
