Hi I've had a bad cold three weeks ago and now I have catarrh and sinus headaches which are getting me down. It's not covid as I've tested negative on lateral flow tests and a PCR test.
Has anyone got any remedies? so far I'm inhaling over a bowl of hot water with menthol crystals in, taking paracetamol and squirting a saline solution up my nose 3 times a day. Thanks
