Hi I also suffer from Sciatica, It's started back up again the last couple of days so I've either lifted something or after the icy mornings, I nearly slipped the other day and somehow managed to keep myself upright, so I think thats caused it again! I do feel for you, because its painful, been up at 5am last couple of mornings, could'nt either turn over in bed or sit up. Been taking Liquid ibuprofen capsules and rubbing some deep heat or tiger balm onto my back and trying to take things at a slower pace when walking. I do feel for you, no one understands how painful it is until its expierenced.
