What's a strain and how can it be managed effectively?

A strain is an injury to a muscle or tendon caused by overstretching or overuse. It can be managed effectively by resting the affected area, applying ice, compressing the area with a bandage, and elevating the injury. Physical therapy and gentle stretching exercises can also help in the recovery process. It is important to avoid activities that may aggravate the strain and to gradually return to normal activities once the injury has healed.
