If you have just had osteopathic or chiropractic treatment for the problem or indeed any other sort of back, shoulder or neck pain, put the theraflex on as soon as you get home, then at intervals for the rest of the day to reduce post treatment pain. If you have been given any exercises to enhance recovery but they make you sore, the theraflex is useful here too. Use the theraflex if you have just had a hot, soothing bath. Baths are bliss for sciatica and back pain sufferers because heat both relaxes the spasms back muscles, which are causing pain by squeezing the nerve fibers threaded through them, and also soothes pain by stimulating the release of endorphins.
