Some of this is TMI so you may wish to look away now. For the past 2 years I have been having weird 'episodes' that occurr about once every 2 months. Suddenly it's like a switch goes in my body and I am instantly incredibly hot, my palms,chin and vagina itch like mad. I have a rising pain in my gullet and a massive stomach ache. Last night I had recently eaten and was massively sick and had loads of diaorrhea, if I haven't eaten recently I sometimes just feel terribly sick and feel like I need to 'go'. Once that has gone off a bit I then start shaking and feel cold and then wait for the stomach pain to subside which takes about a hour sometimes. It's like a mega period pain. Once it's all gone it's gone and the next day I just feel drained and have a sore stomach. I have been checked over with a brain scan, electrodes on the head and all that and they can see nothing wrong. The consultant says it's caused by lack of blood flow to the brain and it's just one of the weird things the body does and they don't understand it but there is nothing they can do. So far they have always occurred whilst I am at home but I'm terrified they will happen whilst I'm out and about or at work. I know it's not like having a serious disease or anything but I'm a bit fed up! Anyone else had this?
