Hello
Before I went on holiday, my next door neighbour an organist was having problems with the scafiod in the wrist, It is a bone/tendon that lacks a good blood supply, so I lent him a Tens and showed him how too use it, He came back to me saying it was working,
Now we have musical days while gardening I hope I will not become sick of his marvelous playing.
All the best
BOB
