Mucormycosis Symptoms Clarity. Help me.

I had covid like symptoms for 15 days after whicb I am going through post covid symptoms like body pain, eye pain, headache etc. I get little bit of heavyness in my left side of face with pain in both eyes. My nose always remain closed due to some infection since many years. The heavyness is more like a mixture of my feelings and my general tendency to lie and sleep on left side. So i am not sure about how should i diagnose mucormycosis symptoms. What is the sequence and the type of symptoms will i get in mucormycosis. Also, in how many days of infections will the fungus develop. At what stage should one consider the treatment is not possible now. Sorry for asking too much. I am a depression patient and with no funds to get consultation from a doctor. Writing here so someone could help me. Thanks a lot
