Whenever I go to sleep at night, I find that I have a pain in my throat when I breathe and then I have to cough for a couple of minutes in bed. Then again, when I wake up, I have another fit of coughing, but that’s it. I do not have that cough through the day. Is this a problem that I must be aware or is it just a passing cough? It is funny, many people I have talked to say that this cough is induced by exercise but I do not really think so.
