I have a mate who has suffered from arthritis since 18 years of age and has been on pain killers all the time. He had the fingers straightened ( screws put in, had his toes done at the same time )needless to say it went wrong and one of the screws is still in his right hand and still on painkillers. He plays a mean guitar but has taken to using a plectrum and does play acoustic/electric. Music is his life ( he has had major heart surgery ) and he just puts up with the pain. Not good news but you can continue. He enjoys the gigs every w/e!
