Sharp pain under my right breast, also my back is hurt in same area. In extreme pain when I cough, I have no gallbladder.

Need more info. It would be helpful to know how long ago your gall bladder surgery was and also if you have fever or chills. I notice you also have a history of pe? Your symptoms are worrisome as they could be consistent with another pe or with subdiaphragmatic abscess. I recommend you see a healthcare provider as soon as possible.
