Hi, I have been experiencing fluttering in that began in my calves, then my forearms, now my thighs are fluttering too. When it happens, my limb that it is happening to feels as though its not there... It s not numb, just feels absent. I do have hypothyroidism, JRA, and cardiomyopathy, and gastroparesis...could this be related to any of those or what could it be
