I have two lumps on my head, on a couple inches above my ear and the other a little higher than that. They are hard, do not hurt, and have been there for at least several years, I'm still not sure when I first noticed them. I always assumed they were harmless because they've been there so long but thought it couldn't hurt to ask what they are or if they're something I should get checked out. i don't have insurance hence me stopping here first. one lump's a wee bit smaller than a dime, the other about have the size. thank you for any advice.
