I have an acute cystitis, amoeba/watery popo, at the same time an ulcer. This three makes my day so down. My doctor prescribe me an Omeprazole since the first prescription for my antibacterial reacts my ulcer badly. . 

Would somebody can tell me if this omeprazole is still good for me. If i am not mistaken one of the side effects of this is abdominal pain? Which is one of my symptoms in cystitis.
