I have had a mastectomy for cancer and in the limp noids as well. I also have stage 4 cirrhosis and at this time can not take chemotherapy . I'm in great pain. I am prescribed OxyContin short release and as well as OxyContin time release daily but the OxyContin is not covered by my insurance and is quit expensive. Is there another time release pain medication I could take that would be as safe for the liver as the OxyContin??
