@christinesallitto, wow, I'm glad that you pushed your doc for the follow up. Sometimes we know that something isn't right and need help to determine what's wrong.
I had a cough that just didn't feel normal. I was having small spasms in my chest especially when I would try to talk. I know now that it was the enlarged lymph nodes pressing on my windpipe and larynx. I was fortunate that the first Urgent Care doc that I saw did a chest x-ray, the radiologist noted the mass in my chest, and the rest was a whirlwind of appointments. That was four years ago, and I am certainly grateful to have this extra time!
