My head has a numb feeling along with an uncomfortable tingling. When I over exert myself it feels like my neck and head muscles tense up. This makes it harder to swallow and makes me feel nauseous. Because of these feelings I haven't been able to exercise but I do work full time. I have lost some of the feeling on my right side from my head down to the top of my legs. I struggle with my balance, coordination, eye sight and I've lost about 35% of my hearing in my right ear. I'm curious to know if anyone has experienced something similar?
