I have a small lump under the skin on the side of my neck. It's hard, and about the size of a pea, slightly posterior to the SCM muscle. I can move it a little bit, and it's not painful to touch. I am a bodyworker, and very familiar with my body. I never noticed this before about a week ago. What is it possible that this could be?
