We wanted one therapist but she was booked so suggested we go to her associate. Nice, young chap but.... last week whatever he did in the stretching, massaging part of hubby's back caused severe pain for three days. This week, the therapist we wanted, came in to check on things and she is so much more knowledgeable that him. Suggested he use lazar for the incision to prevent scar buildup and he replied that he does not use that. He also told hubby that he could pick up things weighing forty pounds as long as he squatted rather than bent over. I just don't know what to think.
