I've been kinda obsessive about going to the gym at least to do cardio. I have been a big fan of the elliptical because its "low impact." that being said.... in the last 4-6wks i've noticed my RIGHT hand/forearm getting numb when i'm on the machine. I don't swing my arms, since that would just be a bad idea. I'm thinking I should mention this to the doc, but is it a sign of something else? arrrrrrrrrghhhhhhhhhhhhhhhhhhhh.
