### input:
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?

### output:

Hello, I can understand your concern. As you are feeling the lump right under your left jaw, it is possible that you have a swollen submandibular lymph node. As it might be infected, you feel pain when you touch it. This lymph node can be infected due to presence of infection in the throat or in the oral cavity. As you are also having pain while swallowing, more chances are there of throat infection and tonsillitis. In that case, you should visit an ENT specialist to have a look at your tonsils and prescribe you antibiotics if infection is present. If the ENT specialist finds everything fine with the throat, you should consult a dentist to examine your oral cavity to find focus of infection present in the oral cavity. If infection is present in mouth like tooth decay, treatment of the infection will relieve you of pain and discomfort. I hope this information helps you. Thank you for choosing Chat Doctor. I wish you feel better soon. Best,
