When I first felt it I thought it was a spot (just below the surface of the skin) but it's not changed in size (bigger or smaller) and it's not red, sensitive to touch or itchy. It's firm and doesn't move. I'm not a worrier and my gut feeling tells me it's nothing but it's been there for a few weeks. I don't want to go to the Dr for something that seems so insignificant. What would you do?
