Wow, I'm really sorry that happened to you. I hope you can reasonably expect now that it won't get worse, at least?

Sorry to hear that. Does it frustrate you when you hear people dismissing COVID like it's a normal cold or similar to the flu?

In my slightly covid unrelated case, intracranial tension changes cause very subtle sharpness/clearness vision changes. So look out for these things, there might be more problems associated with it! Like IIH, CSF leaks or venous stenosis. It can cause a wide variety of seemingly random neurological pressure changes. Beware of substances affecting it like caffeine, weed, fat-soluble thiamine and Lithium. These can reduce or induce serious problems especially if the intracranial pressure is unstable. And while these might possibly be useful, be aware it is poorly understood overall and can cause damage.

Oh the best thing is when you have GERD and it mimics anxiety symptoms and then you have an anxiety attack because of it.

I might have the same, but I'm not sure if it's only due to dry air. I'm currently monitoring and logging the humidity, and then might buy an air humidifier.

I also have more headaches, not sure if that's because of getting older (I didn't even have headaches when hungover when I was younger xD).

The lungs generally take the longest to get better. They're constantly flexing without stop, so it's a slower process to repair.

I'm saying this from experience as someone who has asthma, allergies, and had a cold or bronchitis an average of once every four months or so growing up. It can easily take several months for a general cough to go away.

Don't take any of this as medical advice, but if it's not getting better (or if it gets worse), you should go get it checked out.

I have something similar, and something I noticed was if the air I was breathing was a little cold it made it worse, and a space heater made it better, as well as making sure my back/shoulders were fully covered in a blanket to keep the area around my lungs warm. I'm not sure how humidity affects it but maybe changing that could help too.

When I had COVID I got sharp pains in my left ear (among other symptoms) and in the mornings my head was spinning and lost balance.

Since then whenever I have a normal cold my left ear gets blocked up and rings more. Any my sinus generally are more sensitive. I find it plays up more, as if a minor cold which would barely register previously is enough to trigger slightly larger symptoms.

So, thankfully I only lost taste for like a week or so when I got it in 2022, but the sinus thing? Yeah. That was the worst part. Everything else was minor in comparison. It felt like someone hooked an air compressor to my head.
