What causes tremors with pain in arms, legs, and joint pain?

Hi doctor,

I am a 45-year-old female. I was treated with intravenous Cortisone injection therapy for a week for having acute demyelinating symptoms for almost two months that appeared together with a new lesion at the cerebellum area of my brain. There had been three other there, supposedly migraine type. Lumbar showed oligoclonal zones both in the blood and spinal cord. My problem is that since then, and even if the cerebellum lesion has disappeared, I still experience symptoms not as acute as it had been during the episode, but quite annoying to disturb my everyday life.

I have pain in my left arm and joints, left leg, and joints of both of my legs. I also have back pain and tremor but not always. I get tired very easily. But tired does not mean tired. It means that I start having problems with my balance in the left leg, tingling, eye sight problem, cannot cope with too much noise, argues and fights with family gets me worse. Nobody understands there is something going on. The last neurologist I saw said that it is a matter of stress so he suggested to consult a psychiatrist. My psychiatrist says stress does not cause this sort of pains as I already get a depression treatment for seven years. However, let me say they are gonna get me crazy with all this. Do you have any idea? How I might proceed?
