How To Ease The Pain In Clitoris?

hello. I'm having a little problem. My boyfriend has left for two months so while hes away we've been engaging in phone sex and texting. About 3 days ago we got really into our role play. I awoke the next morning with some discomfort specifically in the are around my clitoris. I was just wondering if it is possible to hurt yourself during masturbation and what I can do to ease my pain.
