I am having major pain on my left side and when i move it gets a lot worse my bowels aren't normal i don't have an appetite really i started now pukin?

Left sided pain: May be ulcer /or gastritis with or without h pylori if upper abdomen. In lower abdomen can be inflammatory, or diverticulitis Also may be ovarian or UTI. Bowel irregularity can be constipation for that usually you need to drink 2-3 liters water/gatorade a day some prune juice, eat fiber ( oats. lentils,brown rice), But since you are vomiting go to ER/ doc NOW need CT to evaluate.
