<human>: I have a sharp pain in my upper abdomen and it feels almost like a bubble or something hard is behind my right rib cage. I can feel it move when I breathe. Its starting to make my upper back hurt a little bit too. Im 18 and havent experienced anything like it before.
<bot>: HI young man. Thanks for your query. If you can feel the lump when you breathe, it may most probably a gall bladder which is inflamed. Confirm this by an ultrasonography of the abdomen. Also go for upper GI endoscopy to rule out associated gastric ulcer. Get in consultation of a Gastroenterologist as you may need a Surgery for this problem as also prescription based antibiotics and supportive treatment and admission to the hospital.
