Been a long time since I've posted a health related worry here and I am so angry at my self for doing so as my anxiety has been pretty much non-existent for a long time.

I was looking in the mirror and I noticed the middle of my neck has a lump, of course I know this is where the adams apple is but it seems larger on the left side than the right. It moves up and down when I swallow. I don't know how long its been there. Maybe it is just something I have never taken any notice of and my anxiety is making it look worse but I am very concerned that it feels larger on one side.

Has anyone else had anything like this?
