I have spinal stenosis and may have to have surgery. Have been having PT which has helped, but I still often have pain which causes nausea. My question, after searching the internet, is what kind of non-narcotic pain killer can I use after surgery? I am highly allergic to codeine and other types of narcotic drugs. A friend just had this surgery and said even after taking 4 codeine pills per day, she was in a lot of pain. If I do have the surgery, I am just trying to plan ahead. Thank you.
