Doesn't hurt to experiment
Sorry to hear about all that 3o3 - I had problems with tendonitis when I went through an Yngwie Malmsteen shred phase. I know a couple of people who've developed Carpel Tunnel Syndrome simply through playing guitar. It's really frustrating when your body won't do what you want it to - I think that's why I've got more into synths and sequencing. The only limits are creative ones rather than physical ones
