Is this a disease??

I get this tingling in my muscles. I also have times when I am laying in bed were my whole body gos numb for a few seconds to were I cant move. Followed by dizziness, and feeling like I am going p out. Also its like I loss feeling over my entire body, meaning there is a warm tingling feeling over my entire body. I have symptoms such as confusion, problems taking in things I am told, and pain in my head. Its really bothering me, I am gong to the doctors Monday, but would like some opinions from you people. Thanks
