A few weeks ago, I noticed a lump in the back side of my neck, more than one inch in diameter, extremely hard, isn't painful and seems to be fixed to my spinal cord. (It's more to the right, however) It hasn't gone away, and I believe that it may be getting bigger.
I don't think it is a cyst, seeing as it is really hard. I also doubt it is a calcium deposit. It also seems to be in muscle (this I am not sure of).
I am 13 if that helps.
Could anyone tell me what it might be?
