It is smaller than a standard pencil eraser.  It just popped up one day a couple of weeks ago.  I think it initially looked like a big pimple.  It is right at my bra line, so it rubs.  My husband has said it's gotten a little smaller.  It's still red, and the center is indented slightly, with a little yellow crust.  I've been coating it with Bacitracin, and Hydrocortizone but it hasn't gone away.  It does itch.  There is no other concern about either of my breasts.  There was a similar spot on my right hip before this one popped up.  It was there for a couple of weeks and then healed & went away.  I had a clinicl breast exam the first week of March and there were no concerns.  I have a baseline mammogram scheduled tomorrow.  I was not even thinking it could be something serious until I came across this, now I'm losing sleep with worry.  Will a mammogram pick up if it's something serious? Could it be something serious?

Before either of these spots popped up my son was diagnosed with impetigo & treated with an oral antibiotic.  I wonder if that could be a concern.  I'm at nature a worrier, so I hope I'm making something out of nothing.  Is it worth making a trip to the doctor?  Could I go to one of these MinuteClinic's at CVS pharmacy and share my concerns?  It will cost me $75.00 to go have it checked out.  I don't want to appear silly, or waste time and money. It doesn't bother me or wake me up when I'm sleeping. I sleep on my front and haven't experienced any discomfort.  Oh, I did find a very, very small black bug in my bed last night.  Could it be a bug bite?  Could it be IBC?

Thank you for any information you could give.
