Maybe the title should say BAD Myofascial PT is BAD.

Sounds like that one you went to was not very good.
keep searching for someone really good.
It may take a time or 2 to find out if they really are helpful or not, and if not say bye bye!!

Basically they should do pain relieving PT modalities first. (heat, ultrasound, low level laser, IF stim, massage, manual trigger point - those sort of things FIRST!!!!
Then
Maybe some gentle stretches - only if no increase in pain or symptoms.
As pain & symptoms resolve , then more active participation by the patient.
