Change in Symptoms

Hello. I have generalized MG for the past 1 1/2 years. For the past 2 months, I get overheated VERY easily from just getting dressed in the morning to walking into my office. I basically sweat more than usual and then lose all energy, similar to when I have MG episodes and had no energy. Has anyone else experiences this? So far, we keep upping my predisone and will do more physical therapy but I am frustrated.
