Suggest Treatment For Sinus Infection

Trying to get over my 4th sinus infection. Needless to mention, I am asthmatic and tends to flare up more as you know with a sinus infection. Had several sx's in the past on my sinus cavities, doc removed alot of polyps. My last sx was 5 years back. Decided to take on allergy injections, but got to the 3rd year and did not seem like it was helping me. Now, continue to have these infections. In addition, have achy legs....hmm...do you think this can be from a decreased estrogen level in my systems, which we all know broad spectrum antibiotics absorb alot of the levels....Hx: Total Hysterectomy....'06...Hmm!
