Hi. My severe pain started and still is in the inner ankle/foot/calf of left leg. Then I had issues with my right and some other problems. Anyhow I have pn but they don't think that is the cause of the severe horrible pain and think it is rsd or something similar. It can happen from an injury or in some cases like mine unknown. A few things for myself and not to say you the original poster the lidocaine patch or lidoderm made me worse cause it rests on your pain area and for me a fan blowing hurts. I agree that having a shot in the area or having someone touch it or manipulate it is a no no for rsd.The last doc wanted to do lumbar nerve block I think to help an I think it is done in the back using xray After my emg/nc I was in a mjaor flare up of pain for weeks.Maybe not much help for you but thought I would add a little
