I would only go to advanced /expert PTs /DCs... not rookies..or DCs in training they just don't have the overall knowledge that is needed.
Some are truly healers and some just do the cracking..

My chiro used PT modalities & had extra training in many things.. (ultrasound, low level laser, IF stim, nimmo, etc) as well as adjustments and the c1/c2 upper cervical adjustment, also called atlas /axis, and elbow, shoulder, wrist etc...
I did a lot of things on my own as well as some regular PT (work comp) and then found an advanced PT that dropped my top ribs down when they had got stuck up due to severe spasms.
Also self trigger point w/ tennis ball
