hello, ive been passing gas, burping and feeling nausea. my lower right abdomen is hurting or pains and the part around my belly button hurts too. i also have hard time urinating. I have seen a doctor and take an ultrasound, everything came back normal, and so i told my doctor i think i have inflammation inside my stomach. since in my country, we don't have gastroscopy, we aren't able to identify if i really do have stomach inflammation but the doctor gave me these two medicine: pantocid 40 compund pack (once a day before i eat) and new lanta DAEWONG orange (twice a day after i eat). what do i do? do i have appendicitis? Is it bad? i am scared of surgeries. please help. sorry for my english.
