I went to the er and got an x-ray of my foot i don't have it to show but it's been 8 days and the swelling hasn't gone down yet they said sprained?

Swelling can last: Your foot is the lowest part of your body there is a tendency to swell to begin with. A sprain (tearing of ligaments in your foot/ankle) causing bleeding and the inflamation that is a part of natural healing process. It can remain swollen for months. It is pain and instabilty that persists that indicates a roblem that needs to be re-evaluated.

See below: What are you doing to treat the sprain? You should be resting, using ice, compression and elevation.

Have it evaluated.: Swelling may last a long time following a foot or ankle injury. An x-ray can show if there is an underlying fracture. The x-rays may be falsely negative initially in cases of small stress fractures. 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.
