Restorative,

I felt exactly like you did with the chest discomfort! In the year and a half before I was diagnosed with MG, I went to see a cardiologist twice for EKG's and all was OK. I thought I needed Xanax to calm down as it felt like a very mild panic attack. It usually happened in the morning when I woke up and wasn't doing anything strenuous. Now, since I had a thymectomy last month, these syptoms have disappeared! I didn't have a thymoma, but my thymus was slightly enlarged. Just something else to keep in mind. Our body seems to know when something is off.
