For the past few months, I have this on and off feeling in my throat (as stated in my last post) It feels like someone is choking me or that my esophagus is contracting and won't let up. I also have this feeling that something is in my throat - it's the worst when I lie down. I'm constantly swallowing or clearing my throat which also hurts. TMI maybe but my breath started to smell today too.. I have really really REALLY bad health anxiety problems and am now worried, to the point where I can't sleep, that I have esophagus cancer.. Any ideas? Im literally freaking myself out - Should I go to the ER to get checked?
