I was rearended 3 months ago and had upper back and neck injuries. When I went to one of my chiropractor office visits yesterday , the massage therapy part of the visit was very painful. I had sore spots and the therapist was rubbing them out. I was crying from the pain when he was pressing hard on these spots and thought it was necessary to achieve benefits if he got the "knots" out. I have some bruises from this therapy session and want to know if this is normal since I've never had bruising from previous treatments.
