To ease symptoms and treat golfer's elbow, rest the affected arm to allow healing. Apply ice packs to reduce inflammation and pain. Use elbow braces or straps to provide support and alleviate strain on the tendon. Perform gentle stretching and strengthening exercises prescribed by a physiotherapist. Additionally, nonsteroidal anti-inflammatory drugs (NSAIDs) may help manage pain and inflammation. If symptoms persist, consult a healthcare professional for further evaluation and treatment options.
