If it's Lupus. it's for good. But with the lupus you can have flare ups then remissions. I have the same muscle problems you have and for me they are pretty much constant but at varying degrees. The doctor can put you on medication that will help.It's weird how one muscle can hurt so bad, the stop. Then another muscle will hurt just as bad, all in one day. So don't think you are crazy. A good rheunatologist will understand these symptoms, so don't be embarrassed to tell him everything you feel. Having a Dr you can talk to can make alot of difference . Keep the faith!
