Hey Nigel! They have something out called a stress ball! It’s a small rubbery ball that you can buy at the pharmacies that they use on people that had strokes. You hold the ball and squeeze it! That might help strengthen that hand of yours and make it stronger too!
Since we know now that you are getting better!:D 😀 I hope to see you performing your music for us one day by posting it on UTUBE! LOL! Your going to end up playing again! Determination my friend! Determination! Hugs
