What to do if i sprained my hand and fingers a couple months ago and two of them are still swollen and hurt sometimes, why?

See ORS: Sprains of the finger joints are common and can cause persistent swelling esp. For months after an injury. See an ors for evaluation and x-rays to make sure there is no old fracture, etc.Pip joint sprains can 'last' a long time but generally improve up to a year after injury . The joints , however, may always stay a bit bigger than normal. Good luck!
