Trillian - it kinda looked the opposite of the posterior thing, like kidney bean, rounded side facing out. Very strange.

Chickybabe - no thats kinds what I had heard which is why I was concerned. I am already wearing a pelvic brace/band for sciatica though so dont kow if its the same thing or if I'd have to choose one over the other.

I am seeing the physio tomorrow night (I have one who sepcialised too thank goodness) and will ask her about it. It hasnt happened since.
