Hi Jak,
This story sounds familiar to me.
Not trying to scare you, but just be a bit weary of them suggesting you may have a nerve problem in your back that refers pain to your knee. I got referred to a pilates instructor that was a physio who was suggesting this. However, my problem clearly came from my knee and ended up having surgery to fix the problem.
I know you've probably been through the mill seeing different doctors, but have you actually seen a sports physician/doctor ? They often have a good understanding of knee problems.
My knee surgeon also doesn't think that seeing a pain management specialist is the answer. The last thing you need is to be drugged out and not functioning properly !
Not trying to scare you, just a thought.
