@b54321 You know, after I wrote my reply to you and posted it, it occurred to me that it may have left some shaking their heads at the nervousness of the staff person who was administrating the laser. She was always so concerned that I might feel the heat -- and that, actually, would have been great, in a sense, because I had no feeling at all on the soles. Then one day when I felt a tickling sensation we both erupted in shouts of near unbelief and cheer. I now have almost normal feeling, which is a blessing, but never regained my balance.
