Hello!I have something on my lower back like a lipoma, a little lump that moves when I touch it. It doesn't hurt all the time, but sometimes when I touch it, I walk, I sit in bed or in the bath tub, it does. I will go to the doctor soon anyways, beacuse I have had it for a pretty long period of time, but I wasn't really bothered by it until now. I would just like to see some opinions on what it could be.
