Pleghm or Shortness of breath?

[hypochondricat]

So last night after an episode of anxiety and an elevated heart rate for a few hours, I woke up suddenly from my sleep gasping with the feeling of something stuck in my throat and had to let out a big cough but I don't remember any pleghm coming out but I could still feel what felt like pleghm in my throat - I coughed a lil more and went back to sleep. I know I'm awake now but I'm concerned something had gotten into my lungs since I've been worrying about getting a clot. I don't think this has happened to me before. I already have gotten exams done for my blood and there weren't any signs to be concerned except my doctor didn't find it necessary to do a blood clot exam since he believes I'm not at risk despite my poor diet and lack of working out. I'm not over weight though and I hardly eat extremely fatty and salty foods.

Anyway, should I make an appointment with my doctor because of this incident from last night or just shrug it off?
