an injury to a muscle or tendon often caused by overexertion
A strain is an injury to a muscle or tendon, often caused by overstretching or overexertion. It can happen during physical activities like lifting heavy objects, exercising, or playing sports. Strains typically result in pain, swelling, and limited movement in the affected muscle or joint. Treatment usually involves rest, ice, compression, and elevation to reduce pain and inflammation. Gentle stretching and strengthening exercises may also help with recovery, along with over-the-counter pain relievers if needed. Severe strains may require medical evaluation and physical therapy for proper healing.
