How can i get best manual therapy for pain on left side of the body?

Diagnosis?: Please see someone for a better diagnosis than "pain on the left" if you havn't already. If you have tried but not gotten better answers, try seeing a physiatrist and ask if they might send you to a physical therapist. Let them know you would like manual therapy (i am guessing you have tried manual work before and had success). That should help with making a diagnosis. It may take a few tries.
