Kh (Las Vegas, Nv) on 12/01/2013: Sea Salt worked for me for sciatica in my left leg. I tried it after reading the Lepore book.
I had been on a low-salt diet because there's a lot of high blood pressure in my family. When I read that I might have a sodium deficiency, I was very doubtful, but I licked my finger, stuck it in a dish of sea salt, and licked the salt off my finger. The pain went away in a few minutes.
At first the pain returned a lot, but I was able to control it every time with salt. Then I started drinking carrot/celery juice and eating a lot more salads, and that seems to have mostly prevented recurrences.
