I am the new friend who recently posted my first entry here about 'going thru the mg dx process'. Since you're all so helpful, I wanted to ask another question to ears that will hear what I'm saying.

Leading up to March 2012 was the period of months where I'd been pushing myself and going to the gym repeatedly, even though the workouts were terrible and left me feeling worse than ever.

During March, our family was on vacation and I'd gone out for a hike, alone. The hike was planned for a few miles, but after 15 minutes of flat walking and sudden aggressive leg weakness, I headed back to the car. As I left the hiking trail, I noticed my chest was hurting (left side top) and my left arm was hurting too.

(**Note: Many years prior I'd had panic attacks so I know what those are. I was thinking far too rationally for it to be that in this case.)

By the time I got to the hotel room, I had broken out into a cold full-body sweat. I wasn't panicking, but instead observing this attack of the strangest symptoms ever. I felt nauseous and out of breath.

My mother in law insisted on taking me to the local ER, where they did an EKG and chest x-ray. They found nothing of note, but the ER doc called my symptoms "exertional". I can tell you that they did give me a nytroglycerine, and after that it felt like my entire body breathed a big sigh of relief.

My question is, is there anything on that ER visit that would have indicated a myasthenic crisis? They did blood work and that too was normal. The whole thing was definitely an event I do not wish to repeat!
