Im 23 and I guess I guess I noticed the lump around the time I got pregnant a couple years ago but seems to have grown and is becoming kind of painful to the touch. It's not round or dome shaped but more oval and flatish. I saw a P.A and she said she didn't think it was a tumor but I'm not to sure. I haven't had an mri yet and can't get one until I have insurance. I'm very scared that it could be a osteoma that might be warring on my skull. Has anyone ever experienced this before?
