Hi, I have been having joint pain in both feet, knees and only my left elbow. I have been to 2 different primary cares, neurology, and rheumatology. This has been happening since February. It keeps me up. Primary care first referred me to Rheum, who ordered MRI of left ankle since he believed that was where it began. MRI showed bone cyst, but not the root of the problem. No recent trauma, sudden onset, constant pain. PCP referred me to Neuro. I am getting MRI of brain and neck to rule out MS but not showing many symptoms of MS. Neuro thinks that it may be fibromyalgia. I am not happy with this answer because I feel there has to be some form of underlying issue that is causing this. Any suggestions
