My nose doesn't get inflamed or turn red after drinking hot beverages in cold seasons.It just helps a little with the congestion in my throat.And I have talked to my dentist about the metallic taste.And apparently it's not Gingivitis so I think the mucus from the post nasal drip would be the only possible cause.And since you mentioned the "now" treatment-heads up I wanted to know if that's specifically for treating the nasal drip or the bad taste ?.
