From what I have been told, bone spurs are little pieces of bone that have seperated from your cartlidge in your nose. When the ent found mine he had put cotton that had a substance to open up my nasal passages in my nose, and then he could look up and actually see them. He pushed on them to see if they caused pain, and it was VERY painful! I had been having headaches about once a month, but for the past few months, I have been having them on a weekly basis. I never did get any answers from the ENT and plan to return to my primary care doctor. I started doing research and found that spurs are often found in people who have chronic sinus problems (despite the ENT insistance that I am not having sinus problems, and that spurs have nothing to do with sinuses). My headahces seemed centered around my forehead, and sometimes under my eyes, and the back of my head. Once my sinuses start to drain I feel instant relief!
