I was diagnosed with CFIDS back in January but in March I went to the ER with chest pain and the chest x-ray and subsequent CT scan revealed a mediastinal mass. Upon biopsy, it was diagnosed as a benign thymoma. I've been doing ok post op but I have this very annoying new symptom....lots of little muscle spasms. Back of my calves, bottom of thighs, forearm, bicep, hand, and toes. It doesn't hurt. It almost feels like a palpitation of my muscle if there is such a thing. I'm 31 and my thoracic surgeon suggested that since I've had a number of neuro symptoms over the last 2 years that I see another neurologist to rule out myesthenia gravis. I saw the neuro, who specializes in MG a couple of weeks ago. He did a full workup and ordered the antibody testing for MG. (acetylcholine receptor and antismooth muscle test)My family doctor also ordered a lupus profile. Everything is negative. Both of the MRI's I have had over the last few years were negative as well. Does anyone else have these strange spasms? Does anything help to stop them? Renee'
