Benny, the pain is real, but what you don't yet understand is that ALL pain is created by your brain. This is a physiological fact. The body part that has the pain is not capable of producing pain. The nerves at the body part send a signal to the brain, and it is the brain which processes that signal and decides whether or not to send back pain.
When I crashed my bike in 2008 and broke my hip, the nerves at the break had to send a danger signal to my brain, my brain had to process it, and then send an urgent pain message back to the site of the broken bone. The pain message told me that it would be very bad for me to move, which was a good thing. The next morning, I had surgery to insert three pins into my femur.
That was a legitimate and important pain message.
However, four years later, my femur is perfectly fine, but farther down on my thigh where they cut through a bunch of muscles to insert the pins, it still hurts. Why? Right after the surgery, when the muscle tissues needed to repair themselves, it was a good thing to have pain, because it reminded me to be careful of the giant slice right through my thigh. But four years later??? I KNOW that those muscle tissues are totally healed. So why do I have pain? What's the point? Where's the danger?
Answer: there IS NO DANGER. I can go to the gym and do squats and lunges all day long, without any danger or injury whatsoever.
The pain is there to try to distract me, because my brain remembers the pain from the surgery. This is what we are talking about when we talk about conditioning. But I know there's no danger from this pain, so I ignore it, and I go to the gym and I do my squats and lunges, and I visualize those muscles being stronger than ever, even if they are hurting while I work out.
You have to ask yourself the same question: Is your pain a signal that you are in actual danger or is it your brain trying to distract you with old memorized pain conditioning?
I can't answer that question because I know nothing about disc bulges although someone, four years ago (I can't remember who, probably my chiropractor) thought I might have a slight disc bulge because I had lower back pain before I discovered Dr. Sarno. But the back pain was nothing compared to my neuro and stomach issues, chronic neck pain, and bad headaches, so I don't remember spending much time worrying about my supposed disc bulge. And I've never had an MRI.
