i don't know if it more stress than normal or what but today at work i had 5 bowel movements, mostly formed but all urgent and a little mushy. then my stomach started to swell up and i was getting rock like cramps that were visible to the eye - like part of my stomach look pinned up under my ribs and the rest was undulating. i couldn't extend my stomach out fully to sit up straight. mind you, i get this symptom every day, but today it was extreme. i was also sweating and itching.by the time I was home I was in tears, could not stand the feeling of my loose clothing on my skin, couldn't think at all, felt hot and cold at same time, was still sweating and itching, and had MASSIVE headache. went home and threw up though i never felt nauseous. more like throwing up when you have a lot of stomach pressure and a headache (like a sick headache).when I get this way, should I go to the ER? i feel full of gas still, but otherwise what is wrong??I don't understand.
