I have suffered from chronic sinus infections throughout this past year. I had sinus surgery at the end of March. Unfortunately, this has failed to ease the pain. My primary care physician prescribed Vicodin to help with the pain. Since then I have had to switch to Percocet because I have built up a tolerance to the previous pain medication. I would appreciate any suggestions about possible steps I can take from here. I am doing all of the normal things to help with the sinuses: sinus rinses, Flonase, anti-inflammatories, etc. None of these seem to help significantly. Please help.
