It’s great that you are wanting to try MFR. However, in my opinion you really need to have a MFR trained therapist to get you started. Rolling on a tennis ball is a great start, but it only a tiny fraction on what MFR is about. The ball is a part of self treatment in conjunction with the MFR therapy to be most effective. I don’t want you to feel disappointed or letdown by trying just the tennis ball as you will not get the full benefit of MFR. Just my opinion and after having been through 9 MFR sessions. I’ve found you need the therapist first, then the self treatment. Good luck either way.
