Sprains and strains are injuries affecting the muscles and ligaments. A sprain is an injury or tear of one or more ligaments that commonly occurs at the wrist, knee, ankle or thumb. A strain is an injury or tear to the muscle. Strains occur commonly in the back and legs.
Sprains and strains occur due to overstretching of the joints during sports activities and accidents such as falls or collisions. It may be due to fatigue or not warming up before an activity.

Immediately following an injury and before being evaluated by your doctor, you should initiate the P.R.I.C.E. method of treatment.
Diagnosis involves a thorough physical examination. Your doctor will inspect the area of injury and see how well you move the muscle or joint. X-rays or other tests may be ordered to rule out fractures or other problems.
Your doctor may prescribe nonsteroidal anti-inflammatory drugs to reduce the pain and inflammation of a sprain or strain. A period of bracing may be necessary. Physiotherapy may be recommended for moderate to severe injuries. Surgery is rarely needed, but may be suggested for torn ligaments and tendons.
Most sprains and strains show significant improvement in about 2 weeks. Severe injuries sometimes take months to heal. Strenuous activity should be avoided for at least 8 weeks to allow proper healing.
