+1 for David Leisner’s book. Alexander, you should definitely get a copy Playing With Ease. In fact all guitar players should read this book. David had to end his performing career for a number of years because of focal dystonia. He is now fully recovered.
I wonder sometimes if I have it. I emailed David describing my symptoms about a year ago and he seems to think I have it. My technique is sometimes effortless. And sometimes I feel like I can barely play a 3 chord country song.
For me, a low inflammatory diet and exercise seems to help astronomically with my guitar playing. And proper sleep. If I do have focal dystonia (sometimes I wonder if it’s all just mental), then it kinda makes sense that shocking the nervous and musculoskeletal system a few times a week with weight lifting and cardio may help reduce the symptoms.
Over the last 2 years, especially with quarantine last year, I was extremely depressed. I was overeating/eating junk food, gaining weight, staying up very late and very sedentary. Even though I was practicing a lot, my guitar playing seemed to be extremely unreliable. Some days I barely felt like I could get through the chords to a CCR song. Then some days I felt like I could share the stage with Steve Vai. It was very frustrating. That’s when I got Lesiner’s book and emailed him. It’s not a quick fix. It will take lots of awareness during practice. As we are trying to fix years or decades of deeply embedded habits.
For me, even more so than the book, my breakthrough came after getting back to my usual paleo diet and dropping a few pounds. I started to feel much better mentally. But it wasn’t til I got back into the gym that I really started to feel solid on guitar again. I’ve also been getting to bed much earlier and generally getting a solid 7-8 hours of sleep. It all works together. I think overall for me the low inflammatory diet is the most critical thing, as the food we eat can drastically affect our lifestyle. Followed closely by staying active and, for me, lifting heavy objects.
There is hope, Alexander. Keep your head up. Get the book. Correspond with David - he’s a super nice guy. Maybe think about changing your diet and exercise routine if you aren’t already doing so. The standard America diet wreaks havoc on most people (it’s obvious with our waist lines, but not so obvious what’s happening on the inside), causing, among other things, total body systemic inflammation. So it kinda makes sense to me that a neurological disorder could be managed somewhat by reducing inflammation. I know it helps me a lot.
Hopefully that’s helpful. Good luck
