I've had alot of pain right above my right elbow for the last 3 months, i had an MRI done and everything is normal. its been swollen at the elbow since then, even my pinky and ring finger are numb most of the time. what can it be? nerve?

My brother had a kind of “floating arthritis” for quite a few years—could never determine what it was—UNTIL a dentist found a tooth that was infected, and had been slowly sending out bad stuff. The dentist took care of the tooth right then, and all the swelling and pain completely disappeared. My brother now suggests always to check about these slow infections for the kind of thing you are experiencing.

On the other hand, numbness could be some kind of nerve pinching somewhere. I was mostly responding to the elbow swelling part.
