Rotator Cuff

The physiotherapist's door was open, so I popped in and picked his brain.  As soon as I pointed at my shoulder, he said rotator cuff.  It is getting worse...  I really should have looked after it better without getting RSI working at a stupid book store!  I don't think driving helped either.  Anyway, I will be doing a lot of rotator coff strengthening exercises for the next months...
