I have a sprained ankle swelling went down some had crutches andboit with air.it has been three months after and i still have swelling and pain?

See details: Have the ankle reevaluated and consider an MRI as the next step.

Have it evaluated.: Pain may last a long time following a foot or ankle 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.
