Ear-Nose-Throat Problems

I started snoring since November 2018. I am very much annoyed with this problem. Please help me cure it completely.

I've been sneezing 5 to 8 times in a go for full day specially in daily morning after Dusting the whole house. I do dusting with my masks on that make sneezing frequency lesser than usual. Also my eye itches, and this happens only indoor. Outdoor I'm totally fine. Got my covid test done twice but result was negative. So I googled these symptoms and concluded to have Dust mite allergy. Is it? I really need help because this sneezing for whole day is supremely irritating.

I feel like something stuck in my right side of throat with tightness and burping forcibly.I have Stuck feeling from last 6 months however now tightness is there with irritation in one side of the throat

What are some recommended medicines (and dosage) to have at home if we see early covid like symptoms (while still waiting for test results for example)? Have heard of medicines like azithral, but wanted a professional opinion.

My throat and toungue hurts whenever I eat even less spicy food or drink normal temperature water it seems to be related to stomach heat not sure

I m covid positive before one month. After the 1 one month I m still not smell and taste due to covid.

Female 23 yr,Allergy ,sneezing & watery nose for 8 months,when she is taking medicine like anti histamine I.e.Montelukast levocetrizine n all , everything becomes OK but when stops medication again allergy like runny nose n sneezing continues.There is no any lungs problem or any other chronic aliments present.she had no allergy issue from birth ,it is suddenly appeared last year.Kindly help,what could be the possible reason?better treatment n tests available?

My left nose is always blocked, not able to breath properly for almost 8,9 years now. Visited pulmonologist but no problem with lungs and wind pipe (taken scan, x-ray). Taking breath easy from pankajakasthuri, sometimes it helps but not in winters. Pranayama is not working, I'm getting yawning and unable to do minimum for 3 mins. If I take a deep breath there is pain near chest. I have no other health issue. Milk and dairy intake increases my breathing problem & bad breath  gives pimples on my cheek all times.

On 19th April this year I had all symptoms of covid and got isolated. I recovered completely without getting hospitalised. Yesterday I observed cold weather and I also have started headache, weakness and some bodypain. Is it can be black fungus.

From last 7 - 10 days. Mucocele at my lower lips. It's not paining but I am getting irritated due to this.
