Not likely: It is muchore likely that what what you describe as a simple ankle sprain was something more. Consider a thorough check and probably an MRI to determine why you are still having trouble. Thanks.

Not likely: You need to get examined. May have torn ligament or osteochondral defect or something else going on. 10 months is way to long.

Unlikely : 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.
