For months now when I lay down at night I can feel a clicking from time to time in the back of my throat, it almost feels like a bubble of air popping. This worries me that it may be related to failure of muscles back there. I only notice it when laying on my back at night, I don't seem to notice it any other time save for occasionally if my head is tilted or something.
About four days ago after I had finished eating dinner and went to get a drink of water. Something happened, I'm not sure what because I wasn't talking or laughing or anything really, but it seemed like the water went down the wrong way. I began choking, hard. I started coughing really badly, didn't feel like I could breathe, and finally I began vomiting. After I vomited it started to get better. This really scared me because I don't remember ever having done that before.
I also have been going through a phase of feeling like foods are going down my throat slowly and kind of painfully. Not every time but frequently enough. I constantly feel like I have a lump in the back of my throat or a piece of meat stuck back there, I feel like I get a good bit of air trapped back there randomly, and to top if off it constantly feels like I've got mucus in the back of my throat just behind my nose. My throat has also felt dry pretty consistently. I think I sound a bit hoarse but my wife says I sound "sinusey".
I've also had some spells where my chest feels tight, almost an asthma like occurrence, which I do actually have asthma.
I'm worried that this may be the sign of some sort of weakness coming on. I do know that I've had some of this happen around March when I was really in the midst of a bad worry cycle and my twitching was through the roof.
