Suggest Remedy For Increased Pain In The Right Shoulder And Back

Hi, I have had my gallbladder removed just over two weeks ago now. They did not find any stones however my gallbladder wall was thickened in previous scans. Since having it removed under a laproscopic proceedure I have been back and forth to my GP who has taken me off of all pain meds and just given me Omeprosolve as I was having extremely painful GERD attacks (acid reflux.) I still feel increased pain in my right shoulder and pain in the centre of my ribcage spreading under the ribs and towards my back. I also still have diorreah and am getting rather fed up of my GP saying theres nothing he can do! I am finding sleeping hard at night as I wake up constantly in pain and can only sleep on one side. Please please please can someone help?!
