Most of us.
This is conditioning at its finest (or worst depending how you look at it). Before I read Sarno I was in pain...left hip, left side dominated (sciatica in leg, lower back etc).
One day at about 3:30 in the afternoon I got a new symptom...the pain switched to the right side!. And it was way more Firey that the left.
So , I'd have dull deep muscle left dominated pain all day til three thirty, when it would shift to right side flames. Pretty ridiculous, but predictable.
After reading Sarno, it all became clear. The day it shifted, I was on a job and totally caught up with my work and on time. I had met and even beaten my deadlines.
...and then the production designer ADDED a ton of new stuff to the set I was finishing, 36 hours before it shot ..... What a DICK! Are you Freaking crazy? Now I am gonna look like I f'd up when it's YOU!
That's what I felt, but I said "Oh... sure boss, I can get that done"
..and My right leg was on fire...
After finding out about conditioning reading Sarno, I really focused on how much I loathed Hollywood, the Production Designer and the whole ego-insane-common sense be damned world I worked in....so when the 3:30 pain came I turned my thoughts to THAT...
..and it was gone in a few days.
This is like being a detective in your own life. Something was said or happened when you started getting that symptom and it is continuing because of conditioning. Find the catalyst, blow it up, no more pain.
