It was the physical therapist. I have a pinched nerve in my neck that they are working to get straightened out. But I was having a lot of bad reactions to "usual treatment" (aka neck traction, where this device holds your head and slowly pulls on it).
So that gal sent me to another gal who is trying these techniques to calm the hippocampus and amygdala in the brain (which is being flooded with cortisol all the time from the fight/flight response).
Somehow pulling on the hair is one of them???? does NOT feel good or ok at all. Karate chopping points on the wrist, ankles, and somewhere near my head which I now can't remember all fit into that "helpful" category.
I'd rather just hang out on neck traction.
