Keep asking around. Other health care providers are good sources. If a massage therapist gains the respect of a medical physician, chiropractor, nurse or physical therapist through personal experience or through lots of positive feedback from their patients, then the person is worth a try. If you are in a location where there are several to choose from and there is a good listing of them in the yellow pages, then look for additional certifications or training in sports massage, medical massage, or other specialties such as trigger point therapy or neuromuscular therapy (NMT). If you are unhappy with a service, then it would be best to end a session early if you want discounted fees or refuse to pay for the service. The therapist is putting forth her/his best effort whether you think she/he is meeting your needs or not. If you eat an entire meal at a restaurant, then complain it tasted awful, would it be fair to have the entire meal for free? If you accept an entire service, then expect to at least pay a good percentage of it. If you are not too sure about paying for a full session, then start initially with just a half session if it is possible (20-30 min). You will know within that time whether or not the therapist is worth the additional cost for another session.
