Black Fungus Query. Of black fungus?

Hi was covid positive on 23 april and in may 10 i was negative. i was on home isolation only. but i developed granular pharnagytis and throat infection and currently under medication for the same. i also do steam and gargle 2 times a day. but i feel some clicking noise on jaw and also sometimes heaviness on nose. there is no nose blockage and no mucus coming from nose. but sometimes jaw also pains and right side of the head also pains. Also i feel some sensation under the ear. I have no fever but sometimes i get cough (very rarely). i am tensed about the right side head ache and nose heaviness and jaw pain and slight sensation under the ear. Can this be a sign of black fungus? Please suggest steps.
