I got food poisoning from home made ceviche with tilapia. I made it on Friday night for a party Saturday night. Took some to work on Monday and forgot to put it in the fridge. In the afternoon it never dawned on me that I forgot to stick my fish in the fridge...and I went ahead and ate it. Tuesday I woke up with a stomach ache and nausea and went about my day. Wednesday (4/27/11) morning hits, and symptoms are worst. I get out bed for my morning run and mid way through I had to run to the bathroom with diarrhea. After the diarrhea, I started throwing up, I had low grade fever, horrible abdominal pains that wrapped around my entire midsection. It kept going like that for all day Wednesday and most of Thursday. Here we are almost a month later(5/18/11) and 20 lbs less. I have a dull stomach ache daily (sometimes stronger than other days). I have bouts of diarrhea and constipation. I can't eat much, and the little bit I can eat is raw food (beans, lettuce, avocado) and bread, crackers, cheese. I don't have an appetite for meat or fish. I avoid all sauces, spices, liquor, citrus acids. Anything that doesn't agree with my stomach aggravates the pain , causes nausea, and feels like acid on my stomach. If I over eat my stomach hurts and I spend the next hour burping. My stomach makes all sorts of weird noises (bubbling sounds, hunger growls, etc...). Since I'm having difficulty eating and digesting my food...severe constipation will kick in and if I push to hard to go I'm thinking I may be over exerting myself and my sugar levels bottom out and I start experiencing a blackout. My health insurance kicks in next month (June). So, I've been holding out and trying to be a trooper. I know something is not right, as this has been going on too long. What can this be?
