I have had pain along my back pelvic region, especially the right side for almost 18 months. I have attended physiotherapy sessions, been referred to the spinal unit to no avail. I am now awaiting an appointment at the Pain Management clinic. I am without pain if immobile, but cannot walk more than 100 metres without sitting down. The pain is unforgiving but, relatively, quickly subsides when I rest. I've no idea how I have done this damage. I am 50 years old and otherwise in fairly good health. Any advice would be very welcome. thank you.
