Hah, I hear you about the inside of the knee. In fact, the whole inside of my legs is over-sensitive and sore. If I get a massage, I always have to ask for flat of hand only in that area. Yet, I don't think my elbow is an issue and I don't have headaches, thank goodness!And let's just say it was a good thing he was standing to the side when he touched the inside of my knee, or he'd be singing soprano!
