Hello,
I experience a brief localized pain sensation, almost knife-like, when I inhale. The pain is localized slightly left of center(my left) in my neck/throat, about two inches below my adams apple 'peak'. One inch above my collar bone and towards the front of my throat. It feels to be 'inside my throat/neck as opposed to the surface.

It is not my carotid artery as I had this ultrasounded a couple years ago and it was perfectly clear. The carotid is in a different location than the pain anyway.

If you were to graph my breathing as a wave form, where the top peaks of the wave represent the moment of inhalation, the pain occurs at the peak, and slightly after; i feel the pain the moment I inhale and slightly thereafter. It does not persist throughout the entire inhalation period, nor does it occur, at all, during exhalation.

I felt my throat for any unilateral or bilateral swelling or abnormalities and my throat seems symmetrical. I don't have a cold nor am I recovering from one. This pain is not in the area of my lymph nodes either, as I am familiar with the major ones in the neck that swell prior to cold symptoms. I have not pulled any muscles in my neck. The pain sometimes doesn't occur for hours, but eventually it will happen several times in a row during inhalations. I am a 28 year old male.
