How long have you had this and do you get frequent sinus attacks ??
I was misdiagnosed with chronic sinusitis and bronchitis for years. Just want to pass an idea along to you.
I have PIDD which is Primary Imune Deficeiency Disease-learned that at age 57.
I did not do well even after sinus surgery and my ENT suggested it. When I was tested , I learned I had a genetic disease. Just wanted to pass that along in case it helps. It is a simple blood test. and if you have more than 4 sinus episodes a year, it is recommended. To learn more go on www.primaryimmune.org
I am treated with IVIG every 3 weeks at home.
