Hi There,

Welcome and I am sorry you are going through this. I too am 37. I has sudden onset of burning tingling and muscle twitches all over my body in August. I've had every test imaginable so far with nothing as a diagnosis. I know how frustrating it can be. I hope that you will get a diagnosis soon. Learn as much as you can and be your own advocate. Don't be afraid to ask Dr.'s for tests you want. And don't be afraid to get second opinions either. Hang in there, you'll get good support here.
