The problem is with muscles becoming fatigued VERY quickly. This used to happen when I worked them very hard but now happens in a few minutes (sometimes less) of doing normal things. They will start with cramping/burning then will get weak and rubbery to the point where I have to sit down or fall down.
Initial strength is unaffected. I have no trouble doing anything I need to do, for a few minutes, then the muscles start to get weak. The burning/cramping can start almost immediately. This happens in muscles all over. It will even happen if I eat something that has any significant resistance. Even eating more than a small amount of something like peanuts will cause cramping and burning in my jaw muscles.
I’ve tried all sorts of supplements and none helped, not even remotely.
I’ve had many tests, blood and neurological (including nearly an hour in an MRI scanner) and all came back negative.
At this point, I think I’m just being passed around from doctor to doctor and have had no help… so I’m trying a different route.
