seriously - for once ...

is it safe?
i'm taking ibuprofen tablets to try and reduce the pain of sciatica which is crippling me at the moment.
i can't seem to shake it off.
i think the tablets are helping take the edge off it, but i instinctively distrust tablets and wonder whether i am setting myself up for side effects.

i've even got a tube of ibuprofen gel to rub into my lower back, so i expect that soon i'll be so full of the stuff i'll be able to drive a six inch nail into my head without wincing.

any advice gratefully received!
