Ugh so sorry, Sue, that you've hit this speed bump and are having chronic issues. I'm glad you are working with a pain clinic, if that works for you. Generally pain "clinics" rotate around medications or injection procedures. Whereas, pain "rehabilitation" centers offer a more holistic approach treating the whole person through cognitive behavioral therapy to help with emotional and behavioral needs that come along with living in chronic pain and finding acceptance. Also, physical fitness and helping to teach proper and safe activity. Reducing chemicals is also typically involved. Just a thought and I wonder if you might consider a different approach one day?

In the mean time...how frustrating to not know the why behind the what. Why are you having chronic knee pain and stomach pain now. It seems doctors have not been able to figure it out. Do you think you've been tested properly and do you feel confident in your doctors having done the best job for you? If so, and you are simply left with chronic pain, here is an interesting video about central sensitization. Dr. Sletten from Mayo Clinic, Florida gives a heck of a break down of the "why behind the what".

I look forward to your feedback and hope you get a chance to watch the video.

How nice that you live near canyon and mountains in Utah. It sounds beautiful and must provide lovely scenery for your walks on sunny days.
