I am female and was 19 two weeks agao. Earlier this year my doctor noticed i had a heart murmur which is yet to be assessed by a cardiologist. I had been experiencing what he believes to be vasovagal attacks where i lose my sense of balance, go completely blind and deaf, get cold sweats and shakes before collapsing. I don't have any known allergies but have developed an intolerance to nuts. I had been fine stuffing my face with them for years but now i can't eat a single nut or anything made with them without severe projectile vommiting and cramping. I often have unexplained diarrhea and nausea which is not fun however, this is getting worse. Last week i had a plain waffle and later i experienced severe abdominal cramping, an overwhelming need to vommit,cold sweats, shivers, dizzyness and then everything started spinning and i kept falling to the left. I fell over in the drive way and i had severe cramping and diarrhea for 2 days and felt weak. This was different to the supposed vasovagal attacks yet this is the first time i have been so bad with food. I felt like i had been poisoned and was dying ! I have eaten waffles earlier in the year and been fine and the rest of my family were fine with this one. I was wondering if i could have become intolerrant to something in the waffle ? I don't have problem with pizza, bread or milk. I have lost a stone in the last few weeks. I don't have gas problems.
