bad back and sciatica help

Accupressure, blew my mind, dude put victims of concusion back together, dis-jointed, during Vietnam .
He had me lay on his living room floor, squatted beside me, and had me push hard against him with my left arm, while guiding me to touch various places on my body.( Not there.lol)
In 3 or 4 places I lost significant strength in my "push", indicating some things I knew but he didn't. Blew my mind .
He adjusted me, pain I had had since lifting hemi heads off in-car engines, was relieved while there on holiday, and once I knew it could be relieved thru chiropractic, that physiotherapy, etc hadn't helped much.
He's teaching at Oxford now.
Thank-you Dr Tony Corrigan .
. For what it's worth .
Good luck .
