Thanking you all very much, for the welcome and the support.
Well I've managed to work out it is a Bier Block that's being proposed.
I'm not quite sure what to make of this, as the IV is put into the affected hand, and as I can't even wear my wedding ring, I'm not sure how I will cope with a needle Equally I'm keen for any intervention that might help.
I'm going to go for one more SGB as I don't think the last one hit home at all, and I guess I'll take it form there. Thanks again
