Hello, first time I've posted. I've had chronic back pain, now widespread pain for many years. I had a spinal fusion 6 years ago, successful at first, then 18 months later symptoms increased again. I've had all the usual Nhs treatment including caudal epidurals. I'm currently trying to reduce my meds which is great because the side effects have been awful. Yesterday I visited an osteopath for the first time, always been cautious about this kind of treatment. I went to a local well respected man who was originally a Gp. Consultation was good, nice manner, seemed to understand my problems. Had a couple of treatments then not long after got severe pain behind my left knee. I've been having knee pain a good while now, but this was different. All night I've had this burning pain, been awake hours. Has anyone else experienced this ?
