I have been having recurrent right ear eustachian tube dysfunction. Was told I have a slightly retracted ear drum...can it return to normal, in time, with using the Veramyst and Sudafed (generic), along with guaifenisen and netipot rinses? I was diagnosed non-allergic rhinitis, so also...is it useless to use Benadryl, or doe Benadryl also help? I want to do everything I possibly can... I am a Celiac and do not consume either gluten or dairy. I take calcium citrate and magnesium malate because I do not eat dairy.
