Suggest Treatment For Cough, Wheezing And Lower Chest Pain

Question: Dear doctor,
I'm a 49 year old female.
It's been a few years. It started about 3 years ago. One morning when I woke and took my first deep breath in, my chest had one sound, as if the air I breathed in cleared up a sand that landed on the way of my breath. In time, the one sand became a few, and now it is an area. It used to be just that one deep breath in the morning then the rest of the whole day is fine.
Now it's whenever I lie down for a little while and take a deep breath. Sometimes in the morning I feel like to cough too, especially recently.
Also, last year one night (3am) my lower chest hurt so much and I coughed so much that I almost decided to go to the emergency room.
In the past few days, my throat feel a little pain.
During the day, I also feel some random pain in my left or right chest when I breath out. Sometimes I feel pain in the center of my chest right next to my left breast, sometimes the pain is under my left or right breast.
My family doctor has taken pictures a few times but couldn't see anything. She thinks I don't have any problem. Each time I was happy to hear that. But at the same time, I know my symptom is developing. Is there any doctor who know about this?
Thank you so much for your time!

I checked on this website. It seems there are a few people have the exact symptoms some posted 2011 some even 2006. So I'm not the only one. But nobody came back to give an answer. Hope that is not a bad sign. Here is the link to the site:
