I had my right hand operated on yesterday and you can see why I wont be doing them for a while
if you are not squeamish here is the type of op I had on the thumb. the broken finger I had last year that did not heal had to be cleaned out
it was fully arthritic and pretty well useless so I opted to have the joint fused together basically 2 ops in the same procedure.
