This has happened a couple of times now, so I'm thinking it might be an indication of something serious.
This morning I woke up around 5am. I was coughing, my chest felt tight and my face felt hot and swollen.
I stumbled downstairs for a glass of water, took an antihistamine, a swig of cough syrup and had a strepsil. Also put some vapo rub on my chest.
One or all of these things worked because it went away and I went back to sleep cough free.
I can't find rhyme or reason, or risk other than a stuffed nose .
I am going to the docs, but wondered if anyone had experienced something similar and what it may be!
