My 12 year old daughter has horrible knots in her neck. I massage them out several times a day, but they are excruciating for her. She sometimes feels light-headed afterwards. Weirdly, the back of her neck is hot to the touch. We are not sure if it is because she is in competitive dance, or sleeping wrong. (we have changed her pillow...knots are better today, but still hot to the touch.) Thanks, Troy Carkhuff
