### Patient: Doctor, I have been experiencing elbow swelling, wrist pain, elbow lump or mass, and even shoulder pain. What could be the problem?
### Doctor: It seems like you have lateral epicondylitis, commonly referred to as tennis elbow. It is an overuse injury that causes inflammation of the tendons that attach to the lateral epicondyle of the humerus. Did you recently engage in any activities that involved repetitive use of your forearm muscles?
