I recently read a book by John Sarno called Healing back pain. I've read so much and seen so many doctors, tried so many meds in my journey to try to get back to work and reduce my pain. This doctor has really helped me. He is in the States, but there is a website with support and help from people he has helped himself and they advise you how to improve your outlook. Basically, Dr Sarno has seen so many of us with debilitating back pain, leg pain, fibromialgia etc and he has developed a process to help without drugs or surgery ( some had been bed ridden for 20 years, others like me, for shorter times).
Frankly I didn't believe it would help me, but as I was so desperate I was willing to try anything! For the sake of £5, why not read it and see if it helps?
There are utube posts and TMSwiki.org is the website- I've challenged friends who were in a similar state to me to read the book, but it seems we are only willing to give it a go when we have tried every other avenue. I didn't believe it would help me, but it DID! I'm now at work part time so working back up! Worth a try?
