I have been having pain on my right side after gall bladder surgery too my back going on 3 months... Nauseated in the morning and generally feeling malaise. I have been also treated for renal cell carcinoma in that time frame.. My doctor found my pancreas has been not functioning properly also... I am not producing Amylase and it might be what is causing the pain and illness in my GI tract... My gallbladder was so bad when the surgeon took it out he remarked about it being very diseased and scarred.. It's possible that it may have damaged my pancreas cuz prior to having the gallbladder removed I had several bouts with pancreatitus... I think many of you might be experiencing this and need to have your pancreas checked out... Taking pain meds and other meds are not a proper solution to the condition.. I am still trying to get treated but my Healthcare system is working at a snails pace... I will update if I can if there is a solution to this...
