My mother is 82 and is very active in the community. a couple years ago she started having lower back pain. The doctors told her she has arthritis and gave her codeine, even though she told them she was allergic. She has tried many doctors and they keep giving her codeine based medicine. She takes tramadol, but she truly needs something else. What pain med could she take that is not codeine based, but will work with chronic pain? Thanks again folks... Sweetpea
