After 6 months of sciatica, I was told by a surgical consultant that I had a herniated disk and was in the 10% of patients who would need surgery. I couldn't walk for more than 10 minutes without being in severe pain in my backside and down left leg into my foot; simple tasks around the house and even socialising were a horrible thought. If the consultant had been at all pleasant/understanding, I would have had an op, but fortunately he was such a horror that I put it off. I tried physio, which didn't seem to help, then ordered this book and went to see an osteopath. They've had an amazing effect. The book really helped calm me down, as I was very anxious & depressed at the thought of my long term recovery. After 3/4 weeks of following the exercises, the pain in my foot had gone completely, and I stopped taking painkillers. I'm still doing the exercises; it is a fantastic feeling to be able to go out for a walk and I can easily do 30 mins. His advice really made sense and gave me a great deal of hope. I was so impressed, I left the book lying around for a friend to read who's been suffering from anxiety/panic attacks, and the general advice has been a great help to him too - it makes so much sense, it seems to put you on track to recover by yourself. I'd highly recommend it to anyone with back pain.
