Did you see my earlier post about what my neuro said regarding steroids vs. hospital stays?

Stress definitely contributes. There is no question. My first symptoms came on during a VERY stressful period.
I also believe I went through a conversion involving my left leg. I started getting strange bruising along the outside of my thigh about three months after my diagnosis. Really bad bruising, too. Looked like someone hit me with a baseball bat. My neuro found no relationship to the disease, and I firmly believe that stress of the diagnosis brought it on. It hasn't returned since.
