I've ignored this but I think it's more serious then I think. For several weeks now the left side of my body has been going completely numb and then subsiding. I saw my neurologist yesterday and told him of it and also told him that i've fainted several times as well while getting up from my couch and from the toilet after a bm. He is very concerned and wants me to see a cardiologist thinking it could be a warning sign of something serious with my heart. I'm now having the same symptoms with a really bad headache too. What should I do and should I go to the nearest ER.
