I fell and my dr says i sprained my wrist but the swelling has got worse no matter what i do and i still can't use it the injury was four days ago?

Injury curve: Swelling in injured tissue often takes 72 hours to reach its worst. Then there is a steady state before tissue healing begins. This is known as the inflammatory curve. You are probably just fine.

Have it evaluated.: Swelling may last a long time following a an injury. An x-ray can show if there is an underlying fracture. You may have a soft tissue injury if it is just a sprain and may have damaged the muscle, tendon, or ligaments in the area. Have it evaluated by a professional and get the appropriate treatment.
