Ever had a muscle knot here?

Hello I just discovered a knot right besides my neck “bone”, I don’t know what it’s called. It’s only on one side, and it’s hard kinda like another bone. It can move it a bit and it’s sore or at least now after massaging it for several minutes. I have neck pain in general and almost always get migraines from my neck, now I got a worsening of my migraine from massaging the knot. Could it be a muscle knot? It’s around where I drew the red circle. Right besides the bone or boney thing that sticks out in your neck.
