I have had a burning/pressure sensation in my sinus cavity for over 20 years. I have had sinus surgery to remove polups but that did not help. Someone metioned a migraine without headaches which could be a possibility since I don’t have headaches. Hot or cold compresses releave the pain for the short term. It doesn’t seem to be dependent on season or part of the country. The sensation is with me where ever I go. I have learned to live with the pain since it has not altered my life style to date. Any help would be appreciated.
