Dear Patty:
Hey...I'm every bit as stupid as the best of us and have become expert at making mistakes. Yes, I have 'tested' my body with starch and my body rebelled all over, but the sciatica I get now is not nearly as severe as it used to be (and it is not just that I am becoming immune to pain).
Sometimes, when I was in a state of guarded semi-remission, I would have sciatic pains just before a waterskiing weekend. There was a healthfood store near my work and I could order wheatgrass juice in advance, so would drink about four ounces: It had to be good for me because it tastes so BAD, but it really seemed to help me get through the weekend. Wish I had known about the NSD and calcium supplementation way back then...
No, the sciatic should not last, especially when you get the inflammation down.
Good luck to you,
John
