After 9 weeks of pt 2xs per week after my Radiofrequency-im STILL IN PAIN DARN IT. my pt told me today that i need to go back to the pain dr. that i should have better relieft by now. my left leg has becoming more of a problem everyday. it feels sooo heavy and i have pain downt to the bottom of my calf, into my ankel. MY pt says i will likely need an injection because he can feel inflamation and stiffness around L5 S1. He believes my narrowing of the spine down there is causing the nerve to be inflamed and that sometimes stretching and PT can open up the pathway for the nerve. but not in my case.
