Elanor, Welcome.

Are you feeling any better? Have you cooled off? Have you had lots of water? Heat exhaustion, if you have it, can be very serious.

If you aren't better, go in. It may be MG but don't assume that.

Also, when hydration changes, so do electrolytes. It could be that your body is more sensitive to changes in electrolytes like potassium due to the MG. Your primary doctor could check that too.

Body aches can be caused by a lot of reasons, including a vitamin D deficiency. Again, it's worth seeing your primary doctor about. I hope you can figure out what's going on.
