Please watch this doc from Queens Hospital explain how to relieve respiratory symptoms. For last 2 weeks I've had all symptoms of C19 (tho haven't been tested) & did this on doc husband's advice. I'm fully recovered & technique helped a lot.

Thank you for your kind and lovely messages! I really am completely recovered and wanted to share a technique that’s recommended by doctors, costs nothing, has no nasty side effects but could help you/your loved ones a lot, as it did me. Stay safe, everyone x
