No idea what it is, but it's most likely not pancreatitis. That's a very very painful disease, and you'd be at the ER no matter what getting opiates if you had that, again most likely. I assume when you say you stopped eating carbs, you meant stopped eating white flour. Whole grains are the staple of a healthy diet, and all the most healthful foods are carbs, such as veggies, fruits, etc. You surely wouldn't want to cut out these, as they are the foods you should be eating the most. You should also know that if you had pancreatitis to any meaningful degree, you'd also have to cut out red meat for the most part, as the enzymes the pancreas excretes also help us digest that. In other words, it's not just a sugar thing, it's also a fat thing. Other than that, can't help you. Pancreatitis does sometimes occur randomly without known cause, but the vast majority of those who get it are alcoholics and smokers. It's possible you just tweaked something in that area, such as when doing abs or reaching. If you're a relatively young, healthy person, that's the most likely thing that happened. While NIH does report a case of acute pancreatitis occurring because of this disease you had, again, if you had that, you'd really really know it. My best friend has recurrent pancreatitis, and he's likely to die of it, and nobody knows why he has it, but because of him I've had to learn a lot about it and it's very very painful. On the other hand, abdominal pain is caused by the virus you had, so maybe it's a lingering effect of that. For all we know, after you ate that huge meal you had a very difficult bowel movement and that tweaked your abdomen. But you know, this is all surmise, and only seeing a doc will probably give you an answer. Where you can't find a diagnosis but can find crazy anxiety is Dr. Google. That's fine when you're checking a diagnosis a doc has given you or medication you've been prescribed etc., but the same symptoms are signs of so many diseases and no disease at all, so Google is just a road to insanity if you're trying to blindly diagnose yourself without some prior experience with what you're researching. The dizziness as well can be caused by the virus you had or any number of viruses. Again, don't have a clue except it's probably not acute pancreatitis. Peace.
