Maia, I also suffer from numbness and tingling, both in my lower and upper limbs. When mixed with the symptoms of MS, I thought perhaps it could be MS, too, since I have a sis with it, and was sent for a brain MRI. The diagnosis was that "there was nothing up there", and I was relieved. But, I know what you mean about being scared. I have no insurance and it cost me nearly $1,500.00 to find out, but worth it to me! Doc figures perhaps it might be a herniated disc, but has said nothing more than that. I know of no way to help with the numbness and tingling. Does anyone?
