I used this at the start of another sciatic episode which usually lasts for at least 2 weeks of intermittent agony. Im really happy to report that, although I had another day of symptoms after use, it just went away. Absolutely amazing for that to happen. Ive been a lifelong sufferer of sciatica so it's a really big deal. Thank you for helping me drop the pain of this awful affliction caused by a childhood injury.
