Im 20 years old, and im in great health. I eat sushi probably 1-2 a week from the same place, and have not had any problems with this (maybe sometimes when I drink lots of water, i get a little bloating, but goes away after a few hours). I went to eat sushi on sunday, and i remember running like 2 blocks (cuz it was raining) right after i had sushi (and yes i had lots of water). When i got home, I had this massive bloating... My stomach hurt like hecK! So i just tried to forget about it... But a few hours later, it got worse! And i felt nauseas causing me to vomit. I vomited and vomited. Felt a little better, but still had the Pain in my stomach, and still felt VERY FULL. Not to mention the fact that i felt very very cold throughout the night (fever like symptoms)Had a horrible nights rest, and at 7:30am in the morning, i had to get up real fast and go puke some more (even worse than the night before). throughout the day (monday) just felt really bloated, and could not go to the bathroom, as if i was constapated. Its wednesday, and i still feel somewhat bloated. How can I release everything thats making me feel like this? Please help. This has never happened to me.
