Hello everyone! Can you please tell me, who knows, I've been having it for four weeks now, my stomach is bloated, all day like a balloon, gas doesn't come out properly, by evening it lets go more or less, and by night it completely goes away, and this happens every day, stool is stable and normal, do you think this is normal if someone had cancer?
