Hello.Thanks for the question.In view of symptoms its difficult to fit it into one particular cause.But of course pleurisy,pleural effusion
or inflammation along diaphragm can cause such symptoms.Its common to get referred pain
in the region of shoulder in such causes.Gall bladder
issues are unlikely to present like this.You can get a chest xray and sonography
of abdomen done.This can help to determine the cause of symptoms.Hope that answers your question.Regards.
