I also have a passage problem on one side. After many years of sinus infections on one side, I finally was diagnosed after a MRI with an undeveloped sinus passage on the problem side. If this side becomes infected, I have had to resort to a 30-day regime of zythromax in order to completely kill it. This is certainly a bad time for many. Different medications treat different problems and each have their own list of possible side effects.
Pharmaceuticals treat symptoms.
Allergy injection treatment treats the underlying cause of the symptoms. It is my job as an allergist to help people find the medication program that will be helpful without being bothersome and to help determine if allergy injection treatment may help. Allergy injections actually change the immune system in a way that reduces a persons underlying allergies. As you become less allergic to pollen, pollen has a harder time causing you trouble. I understand it comes from pigs.
