So the left side of my neck right under my jaw hurts a little when I touch it, and when I tilt my head up. Not bad, just enough to be irritating. Also, I ve been feeling like there s a lump there, and at a certain point if I tilt my head down and to the right I actually have a little bump like when your joints crack. I can feel the bubble like sensation move and feel like a pop in my neck when I do this. I went to the doctors a few months ago with severe front neck pain when I spoke, turned my head certain ways, or swallowed, and the physician gave me some kind of muscle straining test, and with no other concerns, left it at that. Now the pain is back but not as severe with the bubble feeling, when I press on the left it s painful, but not on the right. I m not really worried, but I want to know before I go for another emergency room visit if I ve done something to my neck?
