Does anyone else suffer from sever pain in your back muscles. I was thinking this was pain from overuse/myasthenia, but it seems to be helped by muscle relaxants, while myasthenia symptoms get worse.

I've been doing some research and the two symptoms I have that don't fit myasthenia are this back pain, and myoclonic jerks. Those do, however, fit stiff man syndrome, which is also being linked to the thymus gland and (at least indirectly) to myasthenia. At this point, all I want is some relief as the back pain keeps me awake and is torture when sitting at work (despite the expensive chair they bought me). I guess I'm just wondering if this sounds like myasthenia, or if I should ask my neurologist to look test for the SMS antibodies/investigate this pain further. It doesn't seem to get much better with rest like the MG symptoms do, but antispasmodics help some and that seems counter-intuitive for MG.

Thanks for any help you all can provide.
