Not all are expensive but you will have to do some looking to find them. Also if they give you the story of needing 30 or more visits and want you on any kind of contract then keep looking. I believe in getting regular treatments but you do not need to sign up for 30 treatments to get things going. Sometimes the clinic of any kind that is fanciest or has the all best equipment need to have patients come back a lot.
Good luck and if questions come up you need answer to ask me. I might be able to help.
