I've had this in my left knee since I was five years old. In 2014 my knee was reconstructed and due too this it's left me in constant pain and with osteoarthritis.
I have recently seen pain management and they have suggested I have a spinal block in L2 L3 and L4. They can't say if it will work as they are unsure if it is actually nerve pain. I'm scared as I know this can be a risky procedure.
