I have been suffering from all the associated symptoms of sinusitis for YEARS! Spent one year with a doctor in Toronto going through drug therapy, Flonase, etc. No relief. Gave up. Have developed chronic urticaria, which involved allergy tests. No Allergies. While crusing the net, found that on-going sinusitis has been linked to ideopathic chronic urticaria, so I went to ANOTHER doctor to see if I could get some treatment for the sinusitis, thus relieving my urticaria issue. He took one look up my nose and said he could see what my problem was...dev. septum. My husband said he could have told me that 4 years ago since he has been listening to me trying to breathe since we got together. Had sinus X-rays yesterday, referral to an ENT is forthcoming. Surgery is imminent. How badly is this going to hurt?
