Well as a result of everyone's advice I have been having acupuncture & acupressure along with herbal tablets for the past 5 weeks. I am half way into my treatment and I feel a whole new person. So much of the pain has gone and my quality of life it much better than I could of imagined. A big thank you to all of you that posted your advice. My only regret is I wish I hadn't waited so long to consider chinese medicine. If there is anyone out there suffering with back problems or sciatica, please try acupunture & acupressure, it works wonders where everything else has failed!!!
