What is the primary symptom of lateral epicondylitis?

The primary symptom of lateral epicondylitis, often referred to as tennis elbow, is persistent elbow pain. This condition arises due to overuse or strain on the tendons that attach to the lateral epicondyle of the humerus. Patients typically experience a gradual onset of pain, which may worsen with specific movements, particularly those that involve gripping or lifting. The pain is commonly located on the outer part of the elbow and can sometimes radiate down the forearm, but the defining characteristic is the consistent discomfort in the elbow region itself.

Understanding this symptom is crucial as it guides both diagnosis and treatment. Additionally, while other symptoms such as radiating arm pain, muscle spasms, and reduced arm strength may occur, they are not the hallmark sign of lateral epicondylitis. The persistent nature of the elbow pain differentiates it from other conditions and is essential for establishing an effective treatment plan.
