A sprain is a stretching or tearing of ligaments, while a strain involves muscles. A few general rules apply to most repetitive use injuries, muscle strains, and minor ankle and knee twists, says Dr. Kevin Armstrong , a sports medicine specialist and orthopedic surgeon at UCI Medical Center. Cold reduces pain, swelling and inflammation. Don't wrap it too tightly, or you may hinder circulation. Keep the injured area raised, especially at night.
Gravity helps reduce swelling by draining excess liquid.
A knee twist or injury has swelling, persistent pain and discoloration and causes locking, or makes it difficult for you to walk. A shoulder injury limits your range of motion and has swelling or persistent loss of function. The physician will perform an exam, including X-rays of the affected area, and possibly prescribe physical therapy. Most injuries that occur during athletic activity are not overly serious and can be treated without surgery, Armstrong adds. Get back in the game.
