Feels like something stuck in the back of my throat
a couple of weeks ago, I noticed a sensation in the back of my throat. all I can describe it as, was feeling like a piece of popcorn stuck right at the back. I had not had anything to eat that could cause such a sensation, but I talked myself into thinking that was what it probably was.
I have stuck my fingers down past my tongue to see if I could get it out, but I was unable to feel anything down there with my finger.
although the sharp feeling has since subsided, I can still feel "something", it's like something is still stuck there and I find myself involuntarily swallowing to try to get rid of it. it is one of those niggly little things, if I am not really paying it any notice, I can easily forget about it, but as soon as I feel it, I am always swallowing.
the last day or 2, I have started noticing that I have a dry cough, and in the morning just after I wake up, I have a bit of a sore throat.
any ideas what it might be? should it be something I need to be concerned about?
