It's usually fairly easy to tell if the injury is in the soft tissue just by where it hurts. That's a picture of my problem. You should be able to fix the shoulder and bench press. I hear that every week. Then 10 minutes later, after treatment, they bench press.
Sprained ankles are the same way.
It doesn't have to be this way. The other is an acute traumatic injury that causes inflammation and that leads to scar tissue. That tightness blocks circulation causing more scar tissue. It ends up being the same. You know it seems like just about every person on the street could use this treatment.
