I used to lie on my back with my chin tilted up until I felt a tiny bit of drainage/a crackle. Lie on my side with my head at a slightly weird angle to try and get the same. Press between my eyes while pushing my tongue against the roof of my mouth, then let go. Tap between my eyebrows and the spaces beside my nose (or the sides of the bridge of my nose).

Eustachian tube massage can help a little too. This one is designed for ear infections but the ear nose and throat are connected, and getting one moving can help the others drain.

I can’t handle spice but that might help if you can. Perhaps a little cayenne pepper in some hot soup.

And I had a lot of hot tea and paracetamol for the aches
