Not sure if this is going in the right place, but based on what I found online, I think it's ok?
I have these little lumps on my neck under my skin, they're about the size of a pencil eraser. I've had them for a while, they don't move, they don't hurt, they're just there. You can't see them either, my skin looks normal in those areas.
I had one on the back of my neck right below my hair line, and about a year ago my Dr said it was a cyst (which I don't believe because there was no tests done and I just don't believe it was a cyst). It's still there, except right now it just feels tender, and it's about the size of a half dollar, but if I keep touching it, it'll eventually perk to the little lump again. That's the only one that changes size. I also just discovered one on my left shoulder blade.
I plan on going to the Dr again this week to get some blood work done to see if anything comes up. Is this something to be concerned about, or is it normal?
