Four times yesterday I had these spells or whatever. I first feel it coming on in the roof of my mouth and mouth, then it goes through my body. It makes feel weak, nauseous, weak, hot and sweaty. Once I was outside mowing grass when I felt it coming on, I turned the mower off went inside really quick and dropped to my knees and laid down. It lasted about 5 mins. Once I was in bed when it happened.
