i have unexpected onset of hot sweats, then my body gets really itching especially my tongue, hands and lips, severe lower stomach cramps, diahorrea and then vomitting, this can last for half an hour to 1 hour or so. I take buscopan which i think helps, i then am just exhausted and sleep with a really tender stomach. The next day I'm fine. I have been to see doctors, been in hospital needing pain relief and no one can give me an answer to what is wrong. I cant think of any trends or one specific think that brings on these random attachs.
