Thank you its better today as long as I dont eat.
It is possible the procedure somehow made whatever your condition is worse, I mean, a foreign object is put into your digestive tract and things don't always go perfectly well. But it is also possible that you have developed perhaps a gallstone, or you had the beginnings of an ulcer and it was made worse by what happened, or it's also possible an infection has set up shop in your tummy or elsewhere, or it's just plain your gastritis is much worse. In any of these cases, you must see your doctor.
Also, sometimes after procedure like you had, digestion can slow down, and you may be feeling terrible cramping or constipation-like symptoms, and this is caused by how you have to empty your bowel to have the exam, and then food is slow to go back through afterwards, and this can constipate a person. The three things to do if this is the case is to drink lots of water, eat more fiber foods, and try to do some form of exercise (even walking is good) several days a week. You can also drink Acidophilus milk or eat Activia yogurt from the grocery store, this will restore normal flora in the bowel and might help that pain if it's from indigestion.
There is also a very good chance that the pain you feel is gas. People can get pretty gassy after an endoscope or even colonoscopy, and gas in the guts can hurt like the devil. Therefore, you should take a medicine that releases gas, like an alka seltzer (the kind without aspirin) or tums, or continue the Maalox the original doc recommended, or anything in the drugstore that is specifically for gas. Try eating bland foods for a couple days, too, like mashed potatoes, cream of wheat with milk, plain oat bread, that sort of thing... just avoid hard-to-digest food like meats or citrus fruits or spicy things is the idea. Hope nothing serious has happened, but if the pain goes on for 10 days from the time of your procedure, or gets worse as the doc said, just go on and see your doc! If you have an abscess going on, that is pretty serious.
