I heard Desert Island Discs this morning.  Kirsty Young was doing her usual thing.  Love it.  She was interviewing Keith Richards from the Rolling Stones.  She asked about his hands, and I was curious enough to google a picture of them.  He said they never hurt and he had no pain with them; he just had to play the guitar differently sometimes to compensate.  I was rather shocked.  They look extremely painful.  On the other hand (!) mine look perfectly normal, yet they hurt almost all the time and dislocate frequently.  It’s strange having an invisible illness.
