Greetings jliberi104! Welcome to the Healthboards!
I am sorry about all the pain. If the stomach is reddened drinking more water may help improve the mucous barrier of the stomach. The water should be during the day and not with meals. The most appropriate times for water are up to a half hour before meals and a little time after meals.
Cabbage juice has also been a healing substance for ulcerated stomachs and may be useful if it is reddened. Oatmeal and potatoes might be nice for the stomach. Potatoes and night shade plants might be hard on joints and give pain if one is sensitive. I would avoid things that irritate it such as medicines, vinegar, hot pepper, spices, mustard, ketchup, relish, salad dressings unless homemade without irritating substances, cheese, grease and meat. I might go easy on things hard to digest for awhile such as fats, margarines, butter, nuts and nut butter. Cherries might be useful for inflammation and turmeric. Pineapple might be useful also when the stomach feels better. I would separate vegetable meals from fruit meals.
If the gall bladder has been bothering a person mint leaves might be useful held under the tongue and or lightly chewed. If there are gallstones and the pain is severe for 2 days straight with no hours of let up it is dangerous and could be fatal so an ultrasound might be useful. Apple juice and lemons are supposed to be good for small gall stones but if there are many or large ones it might not help much.
Of course everyone makes their own health choices in life and is in charge of their own health care.
