You know the "lump in your thoat" feeling when you're fighting off crying? I've had that feeling now for a over a week now. It feels like I need to wash down some food stuck in my thoat. A mild constriction and lump feeling on the inside of the throat, within and underneath what I imagine would be the adam's apple. It's very different from a sore or hoarse throat. The last cold I had was last year, I have no cough, and I haven't been taking any medications. This began about 9 days ago, shortly after doing ab machine exercise. I can sometimes slightly strain my neck muscles when doing my workout, but it's very slight. I also have back pains that often times make me sleep sitting up slightly so that my chin rests on my chest. I've had no history of acid reflux or heartburn and eat a healthy diet. Any ideas on what this could be?
