Sinus Nasal (online purchase) I have been battling with chronic sinus, it got so bad after having Covid, I lost my voice, I became extremely sick with the sinus drip, it effected my ears and throat so badly. For a month the doctors have put me on so many well known brands of medication and nothing worked. I started using Quality Health Sinus nasal spray, in two weeks time I was able to breathe again, no sinus migraines, pressure, cough. It's all cleared up. For the first time in two months I was able to sleep I didn't cough myself awake from the sinus drip. Extremely happy I was able to get something that worked.
