Our son had a block done several months ago, by the initial pain dr. who diagnosed him (not the one seeing him now.) They said to let him rest for the day afterwards. However, his current pain dr. at Children's Hospital, when we gave him that history, said he would have had him weight bearing right away after the block. It stays kinda numb for about four hours or so, and I think the idea is to take advantage of that window for pt. After the initial numbness wears off, people have varying degrees of relief from the block. For him, it wasn't enough to make it worth repeating, but everybody's different.
