I don't know any doctors in OK but I tried the TENS unit before I got the neurostimulator. The TENS unit is a 50/50 shot as to whether it will help but you place it on the area that is affected. I have RSD/CRPS in my leg, foot and hip and I would put it directly on my hip in a square about 4" X 4" with the wires X patterned. Also my doctor gave me lidocaine cream which I would rub on the affected area which also helped a bit especially with the insane itchy sensation. Thought I was going to itch my skin clean off! Hope this helps.
