I am a 25 year old male and I lift and exercise daily. I have been having this strange symptom for about a month now. It started out as a very mild sore throat on the left side right below the jaw line. This went away after a week but I was left with mild pressure on the left side of my throat right below the jaw line. It isn't painful in any way, just extremely annoying. I really only notice it when swallowing or if I scrunch my head to my left shoulder (It does not inhibit me in anyway). Additionaly it goes away when I eat but comes back after about an hour. I don't notice it when I wake up in the morning either. I've been to the doctor twice but have had no success for a diagnosis (No mono or strep and nothing showed up in my blood either). Sometimes the pressure extends up into my left ear but again it is not painful just annoying. Has anyone had symptoms like this before? Furthermore, should I be concerned?
PS: I do smoke socially, when out with friends for drinks and such.
