A friend of mine who was in the Vietnam war told me one day to get rid of the pain…he said he was on recon and used to have to sit in the rice paddies for days…the pain up his back and sciatica was so bad he had problem walking…first chance he got to take a back…he would sit in the bathwater in the hottest water he could stand for two hours and just soak…worked every time for me….apparently the very small muscles that keeps my spine aligned were going into spasms tightening and pulling my spine in different directions…hot bath relaxes those muscles and they fall back into place…every once in awhile in the last 20 years, I'll do something to pull them out again..but 2 hours later good to go.
