Hi
I just wanted to add a short post to say that I don't exactly know what sort of blocks you had. If you had lumbar sympathetic blocks then you shouldn't have experienced any loss of sensation of movement if they were properly placed and carried out using a continuous x-ray to watch for the correct placement site.

Nerve blocks are not the same as these sympathetic lumbar blocks and are placed completely differently. They can cause loss of sensation.

I suggest you check the type of block you actually had done and, if you think it was suppposed to be a lumbar sympathetic block then try to find out if you can get someone else to do one for you (even just one) to see how you get on.
