Ear-Nose-Throat Problems

I am having a lump in left side of  throat for more than a month it doesn't pain or increased in size. but sometimes i have pain while swallowing from left sometime mild ear pain as well. I am a heavy smoker. Can it be cancer. please help. I have frequent acidity as well.

My right ear is mildly retracted so i keep getting it checked. I got it checked 5 days back it was good and now when i got it checked it was all red, ballooned, retracted as shown in the pictures. Is it okay and will it heal back ?

From very long time am feeling little pain in my ears, also I feel like ears are blocked, some times it feels like ears are blocked due to mucus.. Recently My throat is started paining too.

I am feeling heaviness on nose without cold and this is happening occasionally at different instances from last few days. What could be the reason?

I don't have dust allergy or body like getting cold often. But since one month, mucus getting formed in left nose say for every 2-3hrs gap. After clearing it up ,again it is formed which is thick in nature. if I pull from nose it comes like a thread.then feels like clear nose. Why does it last for one month? Is this anything serious?? Pls advice

During 2018-19 winters, I had eaten grilled fish a lot. Around once in a week or sometimes even twice. As a result (what I noticed), I remained immuned from basic health issues such as common fever, cold and especially soar throat infection. Just in last two weeks I didn't have fish in my diet and unfortunately I got caught by sore throat and cold. I was wondering if I can get some alternate of fish during summer so that I can keep my health better. I hate sore throat and cold. It almost takes out everything off me. Anything which can help me remain safe from common cold and sore throat. Please note that I have tried foods/fruits which boost immunity such as broccoli, citrus fruits, garlic but they don't give the solution to this problem.

My left ear clogged for last one week. I am not able to hear correctly. I have taken madicine  Gudcef plus (3 days) as consulted with local physician. But problem still remains. Please advise.
