If it is something that works for you and you see improvements then do it.
If there are techniques where you see improvements use them.
It may not be something that is shown on an episode, but there are multiple ways to address different situations. Different approaches work different for different people and different areas of the body.
Seeing a practitioner is very beneficial. It is a skill in and of itself.
I have had some graston done on scar tissue with improvement.
