Some of the ques­tions you can ask in­clude: how the pro­ce­dure will feel; an es­ti­mate on the num­ber of vis­its you will like­ly need; the cost of each vis­it (this will vary from place to place, and it is best to call around); the length of each ses­sion; how long they have been in busi­ness; and the num­ber of clients they have treat­ed.
