Why do I feel sensation in bronchi without coughing?

I am 17 year old female, I had a common cold that started with sore throat week ago and now I don't have a cold anymore, I didn't have cough during the cold (my throat was sore for the first 2 days but then on third day my nose started to be stuffy and I didn't have sore throat or cough at all). But like 2 days ago I started to feel not pain, but like weird sensation in area of bronchi, but its not pain, just like a sensation I feel when I breathe. Its not all the time but I noticed it. I don't have cough, or any other symptoms and my cold is like 90% gone at this point, but I don't know what that sensation might come from and I don't think its bronchitidis since I dont cough, I dont have fever, and I feel generally good, just sometimes when I breathe I feel that sensation in area of bronchi as I mentioned and it doesnt make me cough, just like sometimes to slightly make that cough sound but its not cough if you know what I mean. What could be the cause and how can I get rid of it? Also, I dont know if its going to help but I sleep on my left side every night and lately I think it caused me a bit of pain in shoulder/upper chest area from being in that position all night long. So perhaps could It be caused my some pulled muscle or something from sleeping in wrong position ? Thank you for your answer.
