Thanks for the suggestion, Jack, but a wheelchair would not work well in the city. Susan Christiana mentioned a cane which I have also considered. Would be easy to carry and although it would not take care of the problem completely, it may help enough to get me through. Even if I improve greatly before leaving, I may take one just to have in case I get a flare up. With all the walking and stairs, I am sure to aggravate that nerve again.

I so appreciate your good wishes, my friend.
