I was covid positive on23 april but started getting 0 symptoms on 3rd may and came out of isolation on 10th may. but after a 2 week i started feeling pain in throat and consulted a doctor and he told that it is a throat infection. endoscopy was done and it was that there was swelling near vocal cord and some lumps on my throat. He prescribed me medicine and more details in the prescription attached. now my throat pain is gone the lump is also become smaller. but i hear clicking noise in my jaw when i open my mouth. also i feel heaviness on my nose for some time. also sometime my head feel like pulled (sar khichta hai) and there is slight pain in my right side of the head. I am under medication but is this sign of black fungus and should i do some test or treatment for it?
