Hi,
I noticed my twin sister vigorously itching her thigh last week. When she moved her hand, I saw a cluster of tiny red dots. Then, maybe two days ago, I saw a big bruise there. I asked her what it was and she said it was from scratching. Tonight, she was in the shower and called me into the bathroom. She told me not to freak out, just to look at something. She showed me her arms and her upper thigh. One arm had a long, like, swath of the little red dots. The other had a really dense patch at the inner elbow. Her upper thigh had a patch that looked almost like road rash. She got them while itching in the shower. I've looked them up. I think they're called petechiae. Google makes them sound like a death sentence. We are going into finals and I don't want to freak her out. Should she see a doctor ASAP or can it wait two weeks until finals are over? Also, she takes advil PM all the time as a sleep aid. I've asked her not to, but she does it anyway. Could that have anything to do with it? She's 22 and has a prescription to some kind of ADHD medication too.
