Sprains and strains are common injuries that share similar signs and symptoms but involve different part of your body. A sprain is a stretching or tearing of ligaments, the tough bands of fibrous tissues that connects two bones together in your joints. The most common location for a sprain is in your ankle.
A strain is a stretching or tearing of muscle or tendon. A tendon is a fibrous cord of tissue that connects muscles to bones. Strains often occur in the lower back and in the hamstring muscles in the back of your thigh.
Common causes are sports related injuries as well injuries for over-doing and excessive activity beyond a person’s normal capacity. It also happens due to trauma or accidents resulting in extension or pulling of muscles or ligaments beyond normal range.
It is also common when athletes don’t have proper sleep and are sleep deprived, in addition a proper warm up before any exercise is also very important in preventing these injuries.
