Seemingly random episodes of extreme nausea, profuse sweating, racing heartbeat etc.

Hello Everyone,

I am seeking some help diagnosing a strange issue that I’ve been having since I was about 10 (now 19). 

Basically, I experience roughly 5 minute long episodes of extreme nausea, dizziness, sweating, clammyness, racing heartbeat, and even sometimes impaired vision (blurry/black). I also tend to experience quite intense blocked wind after and muscle aches as well as strong fatigue. These seem to be completely random, I have had about 8-9 of them in my life and they have been at various times including during regular classes at school, after dropping something on my foot and most recently at a party whilst fairly intoxicated. There is no discernible pattern and that’s what sucks.

I know it doesn’t sound like a particularly bad problem and when they happen I remain very calm and in control of myself, but after several years i am more bothered by the constant fear of one happening during something important or embarrassing. Other than this I am a perfectly fit young man, exercising 3-4 times a week and maintaining a balanced Vegetarian diet. The only history of something remotely similar in my family is my mother’s IBS. So any help in diagnosing would be much appreciated. I have pretty much quashed any possibility of it being a panic/anxiety attack, hypoglycaemia, low blood sugar, heat stroke or dehydration.

Many Thanks,

Joe
