I have been suffering with asthma for about 20 years. I then developed chronic sinus infections and bronchitis. About 5 years ago, I had sinus surgery to remove nasal polyps. About this time, I also started allergy shots. Due to insurance premiums, I stopped taking allergy shots. For the first time in years after surgery, I could breathe out of both nostrils. The allergy shots did help to some degree as well. The bronchitis and sinus infections reduced dramatically, but slowly came back. I use the netti pot and must say that it is very helpful (at times). I use a symbicort inhaler from time to time and notice my asthma kicks in when it is cold or when I exercise. I have never had asthma so bad where I needed a rescue inhaler, but nonetheless, I am tired of my condition.
