Strain VS Sprain

Strain

Muscle strain or muscle pull or even a muscle tear implies damage to a muscle or its attaching tendons.
Sypmtoms -->
:: Swelling, bruising or redness, or open cuts as a consequence of the injury
:: Pain at rest
:: Pain when the specific muscle or the joint in relation to that muscle is used
:: Weakness of the muscle or tendons (A sprain, in contrast, is an injury to a joint and its ligaments.)

Sprain

Ligament sprain Ligaments provide connection between bones. Sprains are injuries to the ligaments.
Sypmtoms -->
:: Swelling because of increased fluid in the tissue is sometimes severe
:: Pain because the nerves are more sensitive: The joint hurts and may throb. The pain can worsen when the sore area is pressed, or the foot moves in certain directions (depending upon which ligament is involved) and during walking or standing.

:: Redness and warmth caused by increased blood flow to the area
