You do need to go to a doctor, just for your peace of mind.

My daughter Lindsey had a lump in her breast, scared me. I took her to the doctor and they done ultra sounds and then done a mammagram(sp?) can't spell. The decided it was nothing for her to worry about. I was so worried about her. She was only 17 at the time and it really put a scare in me. It did go away by itself.

Please do see a doctor, like somebody else said it is better to be safe than sorry!
