Expert Q & A Answers About HIV herpes sore

Is it possible to catch HIV through a healing cold sore (oral herpes)?

The other day I had oral sex with a girl (I went down on her). I had a healing cold sore that had formed a scab and wasn’t bleeding. She wasn’t bleeding, either, but now I’m concerned that I’ve put myself at risk for HIV/AIDS. Is it possible to get HIV through a healing cold sore?
