We discussed the frustration I dealing with my sinus trip, between the Sudden cold, and heat put on there ate a lot of particle floating in and out of air. We are planning buying a air Purifier that can at least remove some of debris. I have a appointment scheduled weeks, to test blood since my fit D was low ,to see if there has been progress.
