Myalgia refers to muscle pain that can occur in any part of the body. It can be caused by various factors, including overuse, injury, infections, or underlying medical conditions. Symptoms may include aching, stiffness, or tenderness in the affected muscles. Treatment for myalgia often involves rest, ice, and over-the-counter pain relievers. In some cases, physical therapy may be recommended to help strengthen the muscles and improve flexibility. If myalgia persists or is severe, it is important to consult a healthcare professional for further evaluation and management.
