Hi, I've had mild pain to the left side of my belly button on and off for two years now. It comes goes every few months. It lasts about a week each time. It's mostly discomfort and no so much pain. But recently I found -mostly- dried blood in my stool. I'd say about 2-3ml maybe? Then I had healthy stools for a day or two. Then found a drop of dried blood again in my stool. I'm not sure if the abdominal pain and this are related. I got an ultrasound a few months back, I came back completely normal. It would be of great help if someone could tell me what this could be, tell me what my next step should be or point me in the right direction. Thanks. PS: I'm 26yrs old and I'm a smoker.
