I've was diagnosed with a UTI last night and the pain while urinating seems to have gone away but I keep having these horrible pains in my upper abdomen and I can't hold anything down when I eat, I just keep vomiting. Earlier I puked up some mucus and there was a bit of blood in it, not much but it was still kinda scary. I don't know what's wrong with me, I can't even sleep. And it's not a problem with my kidneys because they ran tests on me at the doctors for that.
