Just like any professional (or human), not all physical therapists are created equal. Have you ever been to an incompetent dentist or hired a bad plumber? I have done both - one who told me I had 5 cavities when I had none and one who told me I had to dig up my garage to find a pipe when it was located on the complete other side of the house and required no digging at all. Before I drilled into my healthy teeth or hired an excavator to destroy my garage floor, I thankfully got a second opinion.
