Hello there patient.
As explained by you can you please share the photo of the medicines you took for covid.
If you have taken higher steroids dose for longer time then I am afraid you may have black fungus infection. (mucormycosis)
BUT DON'T DIRECTLY COME TO CONCLUSION THAT YOU ARE HAVING MUCORMYCOSIS. Because swelling can also occur due to some medicine and which is completely cureable.
I read your symptoms so they kind of match to mucormycosis. I have suffered through mucor post Covid I don't want you to feel the same.
Let's first see through your reports and medicine history and come to a good conclusion.
