Since a few days ago I've had a kind of heavy congestion on my lungs that's really bothering me. I've tested negative but I'm not going anywhere anyway as feeling off-colour. Part of me wonders if the result was a false negative or if I had covid without knowing previously and this is the aftermath.
I've got a phone GP appointment on Monday but until then does anyone have any suggestions about anything OTC for clearing it? I don't have a cough but if I make myself cough something will "come up". It's very weird.
