Stomach ache, like I had when I had a gall stone..?

It is possible to develop a stone in the bile ducts and the pain would very much resemble the pain when you had your gallbladder. This does not happen very often. It could be lots of things so if it worsens then you will need to get checked. To see if you have stone in the ducts a ultrasound or CT scan can be performed and your lab values would be done too.
