My son has sciatica and his last bout of it came when he was on a 4 1/2 hour flight. He believes strongly in chiropractic and he apparently has a good one because this one manages to relieve my son's pain every time, so he called and they squeezed him in. Like you, he's tried pain killers and muscle relaxers, heat treatments, cold packs, acupuncture, etc. and nothing worked until he found this chiropractor. I feel that he's fortunate because I haven't found one yet that hasn't caused me more pain than I went in with but he swears by him, so maybe you'll be as lucky. Sorry that you're in such pain, girl.
