NASA I gotta disagree with you The woman that does my DTM is about 105pounds soaking wet and you do not want her to lay her hands on you. I am a very big guy and she can get trhough without any problem. The second I went to her I swore off the chiropractor for ever. I have a slipped disk in my neck and nerves that have been severly damaged my tens unit, chiropractor, and physical therapist can't help me as much as her.
