Hi, I'm 23 and 115 pds...5'4... I have been getting dizzy when I lay down... like extremely bad... once.when I was cooking and I come close to passing out. I started sweating n almost threw up. I was extremely dizzy... I have an 11 mths old so I can't have these symptoms n take care of him properly. I need answers... if it helps I have a knot that popped up on the back of my n it all started when it came up. It's been a little over a week now.
