Ear-Nose-Throat Problems

I'm unable to breathe fully from my left nostril. Right one works just fine but the left one only functions 20%. What's the issue and what are the possible solutions?

My father in his late 70 has partial loss of hearing. This has been there since years. Now it had increased a lot. Please suggest a doctor or the necessary course of treatment.

I accidentally discovered a small movable lump on left side of my neck about 2 weeks ago. It isn't visible from outside but is pallapable on pressing. Regarding size i am not sure but it's almost constant I think. It moves within a defined region like as it embedded into something which restraint its motion. Its on the trapezius muscle, outside of the posterior triangle according to me. I am confused whether there is any lymph node there in that region or is it anything else. Quite worried about it as I have health anxiety. Attaching the picture please tell what it could be and what to do?

My left ear Eustachian tube blocked due to cold since last 4 days and its start paining slowly. Please provide a medicine.

I am having persistent episodes of burning pain in only left side of throat left ear and nasopharynx area and lower left side of lip since 2 years. Did multiple  test CT PNS, neck USG, CBC, ESR, LFT, ENDOSCOPY, Throat culture, Urine, renal etc etc. Nothing serious found. Visited almost 10-15 doctors but no solution found. For some it is silent reflux, for some glossopharyngeal neuralgia and tonsillitis. I am exhausted completely now. What are options left for me. I searched google and it is saying it can be CANCER, i am terrified and depressed. I am attaching my throat pic.

While I swallow food I think thai it comes up and goes the wrong way. Does it enter into lungs. What to do
