Hi Elzie, welcome to the forum, and I'm really glad you found us and Dr. Sarno and that you're doing the SEP!
I encourage you to read the stories in the
Success Stories subforum, where people often describe what they did that worked for them. There are many ways to do this work and many ways to recover.
To answer your specific question, the key is to discover the negative message that your brain is giving you, and to replace that with something more constructive and positive. What has worked for me is the message that I can't hurt myself because there is nothing structurally wrong with me, and that by doing the activity anyway, I'm helping my body to recover.
I've also had success by meditating on the "other" side - for example the arm that isn't hurting, and visualizing that same lack of pain in the arm that is hurting. This takes a bit more time and concentration than the "message replacement" technique. It is, in fact, a mindfulness meditation, where again you are recognizing and then clearing your mind of all of the negative chatter and concentrating on the positive outcome that you want to visualize.
Yesterday and today I've been posting the link to an excellent movie that came out a year ago, called
The Connection by an Australian journalist named Shannon Harvey. Shannon recovered from a serious auto-immune condition (I believe she was diagnosed with lupus) by using mind-body awareness, knowledge and techniques. She's offering free streaming of the movie for one week to celebrate the one-year anniversary of its release.
To view it you're asked for your email address, but I've been on her list for more than a year and I know she doesn't abuse it - she sends maybe one email a month, whenever she posts a new article on her blog, so it's always good new information. She's in Australia, so I'm not entirely sure when the free viewing ends, but I got the email announcement yesterday (West coast USA) so through next Tuesday sometime. I have the DVD which I bought last year, but I watched it this morning using the link and it streamed flawlessly to my tablet. It's a little more than an hour long.

Finally, the other side of recognizing and replacing negative self-talk is learning to accept yourself, forgive yourself, and truly love yourself. You need this so that you know in your heart that you deserve to recover.
There is a ton of great information in the movie, and a ton of great information on the wiki and on this forum. Take full advantage, keep posting, and tell us how you are doing!
