I too suffer from sciatica, from buttock to ankle and in the small of my back, sometimes to the extent of falling to the floor with no prior warning at all.Ibuprofen helps me, but of course you can't take it, but I do find that sitting at the PC brings on an attack, so I have an egg timer beside me which goes off every 10 -15mins. to remind me to go walkabout. It is amazing how the times flies on here, and since doing that I don't seem to have half as many attacks.I suppose it is a repetitive strain injury because of the way I am sitting. I have tried several chairs, cushions etc. but moving around helps the most.Maybe not at the moment for you, but something to bear in mind when you are over this attack. You have my sympathy carlton,hope you are better soon, rosy.
