How Can Severe Rib Cage To Low Back Pain Be Treated?

I had a cervical historectmy (tho still have my overlies) on the 10th April of this year. I also had my cervix removed and a arterial repair. I have severe under the left side of my rib cage and penetrates towards the left side of my belly button and also into my back. It is uncomfortable more when I am laid down or at a angle when laid up in bed. The pain in constant, and I cannot stand for long either because of it. I have been back to see the surgeon who merely said he is a gynaecologist Only, and to visit my gp. When I did this , my gp told me to go back and see the surgeon!! I am in considerable pain and just keep getting sent either back to see one or the other - yet no one dus any tests! Please can you help?? Thank you
