Question: I'm 44 years old male. I have had frequent problems of sore throat always. I was a regular smoker till July 2014 but then I limited my smoking to parties only, almost once per week. Even though after quitting, I was having throat infection in gaps of 5-6 months that I felt was normal.
I again started smoking in August 18 but in very limited manner i e 1 or 2 cigarettes per day.
Since Dec'18 I started having regular sore throat and I decided to quit permanently. Later on I developed throat infection with itching in ear. My ENT specialist examined and advised anti biotics and other medicines for 5 days and repeated with lesser dose for5 days again.
Now throat infection is OK but I feel sensation in ear and very mild pain on left side of neck and a swollen lymph node below the ear on bottom of neck.Though as far as I remember this lymph node is present since my childhood, but due to nervousness I am attentively noticing it. I feel heaviness on left side from ear to neck and throat. I feel dry mouth continuously and sometimes feel tonsilitis like thing on left side of my throat. I again went to ENT specialist and he advised Hydil 10 for 10 days after physically examining the ear and throat. Which I have just started taking.
Due to dryness I also notice very mild nose bleeds, mostly after waking up in morning.

Some other things which I would likd to mention here are-
Almost similar type of problems were faced by me when I quit smoking four years back.
I drink lemon honey with lukewarm water daily in the morning.
My weight is stable for the last few years at 76 Kg and I don't have other symptoms like less appetite, fever and sweating etc.
I have been diagnosed with mild cervical spondylitis few years back and frequent neck pain and head aches are associated with it also.
I have also occasional problem of tonsil stones.
I drink alcohol in moderate quantities i e 3pegs once a week, occasionally twice.
Please suggest me what should I do.. Is there any possibility of some serious problem and what should be the course of examinations to rule out the same.
I am very scared of this situation.
Please help
