Back and Rib Pain after Breast Cancer surgery?

I had Breast Cancer surgery two years ago, since then I have so much pain and aching on the remaining breast side, I was large breasted and feel the weight from the remaining breast puts a large strain on my back and ribs, does anyone else have this problem or know of a way to receive some relief from the pain other than pain pills or have the remaining breast removed like someone already suggested. I have always been larged busted so I realize there is quite a bit of weight pulling from the remaining breast, this has become a real problem for me with a great deal of pain, also keep in mind this is not a joke I am very serious, I needs ideas of some relief or maybe agarment I can use for supporting my back or remaining breast, open to good suggestions
