question: I have chronic sinusitis (for 10+ years) that is often accompanied by a sticky, weepy eyes at night and a itchy, burning rash on my face and neck.  My sinuses drain during the day and no significant blockage shows up on CT scans.  My doctor thinks I may have allergies and has given me steroids and antihistamine nasal sprays that do not seem to help.  I do get some relief from saline flushes, but they are not capable of curing the problem.  My facial and neck skin are horribly aged due to the rashes and dry skin.  I would like to get a biopsy from my sinus and figure out what this is once and for all.
