Well, i woke up today and had really bad pains in stomach, so i tried to go to the toilet but there was nothing, so i thought i got some paracetamol for the pain, in the space of about 2 minutes i started to get really faint, and got bad cold sweats, i lay down on the floor because i felt like i was about to pass out and then when i got up, i felt really weak like i could barley walk, i then felt nauseous and was eventually sick, after 5 minutes or so i went to the toilet again, i had light diarrhea, after then i thought the best thing was to lay in bed, so i tried to sleep it off, and eventually fell asleep, when i woke it i felt fine, but this all happened in the space of half an hour and i felt so awful, i just wanted to know could you tell me what may have triggered this?
