The Doc says it runs about 30% end up having surgery, the rest about half and half with those that return for 3 or more injections and those he never sees again after the 1st one. He's thinking since I don't get the radiating pain down the leg but once in a while, I'll probably need more than one but won't need surgery.
I just asked him to get through 4 more years at work, then I retire and don't give a shit.
