<s>[INST] Hi my name is Darin. I am having surgery on my nose Thursday. They are doing several procedures. I also have 4 bulging discs in my lower back and I take Percocet 10 daily for chronic pain. My surgeon said he was aware that my immune system was down to Percocet because I have taken it for so long. He said he would take care of me....do you know what he might prescribe me? I have panic disorder and I am almost crippled with fear of hurting and the pain killer not working. [/INST] HiT hanks for using Chat Doctor Percent contains oxycodone, and it does not affect on immune system. It is a painkiller and like other painkiller, you can take. If your surgeon wants to change it, then it is difficult to judge which painkiller he would prescribe you. For panic disorder, you can take antidepressant with low dose benzodiazepine. You can also try some relaxation exercise. In case, you need further help, you can ask. Thanks </s>
