Hi Sarah;
I havent had any trouble with my knee's but after I fell on my shoulder a couple of winters ago(dislocated it) I get bursitis in it every year now. Ive had some pt but it didnt help just made it worse and so far resting it, getting a shot and keeping it warm and it passes in a few weeks. Hope you get some answers soon. It shows up in a scan really good but sure hurts like hell. Take care Sarah.
Gentle Hugs
Karen
