My name is Steve I have been locked in chronic pain for 3 plus yrs after TKR , I have tried every procedure there is to end or relief the pain too no good results. I now am being seen at UPENN PAIN CENTER where a pain psychologist turned me on to reading ' MANAGING PAIN BEFORE IT MANAGES YOU' 4th edition by Dr. Margaret Caudill. Well I would say any suffering from chronic pain or acute pain should look into this book. Information about pain and tools to use against it are there. Reading it seemed to be reading something that was written just for me.Dr. Cuadill's approach to help is well worth the read. Stay positive, move and best of luck . STEVE ROSA
