I was told for years by V.A. doctors that I had a deviated suptum. For years I took drugstore nasal spray to clear my nose so that I could breath. One day out of nowhere, I sniffed some hydrogen peroxide up my nose. Haven't used a nose spray since, only the proxide. Also, the V.A. sent me some Nasalide for a nose spray. It gave me a sore throat and now they tell me that I have throat cancer.
