I have been diagnosed with long covid (10 months now). It's left me with adult onset asthma when I previously had no asthma at all. This is being managed really well now with Fostair. However the whole time I've had post nasal drip. Constantly having to swallow, clear my throat and I can feel it. It's horrible! I've been prescribed steroid nasal sprays, antihistamines, I used a humidifier and I've gargled with salt water and done nasal irrigation. Nothing works. It's making my throat very sore especially at night which is horrible. I just want it gone. Can anyone think of anything I haven't tried? Thanks
