<s>[INST] I have a lump, its more of my shoulder than my neck. But its not in the back area of my shoulder. If u were to run if finger down from my ear the Kim as  just as my neck turns into the top of my shoulder, almost closer to 2 inches down from where my back hairline stops. I popped up around 4am while I was working. [/INST] Hi, Dear,Good Evening, and Thanks for the query to Chat Doctor.
