Oh, I know that the odds strongly favor it being nothing, but I am a chronic worrier, and though my therapist and I are working on that, the imps of the perverse are hard to shut up. I know that at the worst, it's probably a cyst, since I am already a cyst-y person, but... My mom spent nearly two years painfully deteriorating and dying from breast cancer. It leaves a mark. Thanks for the vote of confidence, it's appreciated.

Just got off hold with the doctor's office -- and it was a screw-up. They'd misread my permissions and thought they weren't supposed to leave messages. Everything's fine. Now I assign to Mordor idjits who think they aren't supposed to leave messages who leave cryptic and ominously uninformative ones instead.
