Hey Doc, I keep getting cramps randomly all over my body, even in weird places like my face, neck and back of my head or on the upper side of my head. I am most worried about it on the back of my head (near the cerebellum) and on the upper head. It pains a lot and there is almost nothing I can do to prevent it. It occurs more frequently while I am lifting weights in the gym or after getting less sleep or when its very cold. It almost paralyses me and only stops when I start taking deep breaths. Is there some kind of problem? Should I consult my doctor or get some tests done? It really worries me. Also, is it normal to get cramps in the neck, because even thats scary. Please guide me on what action to take.
