I’ve tried to get in touch with Troy Grady in the past about creating a category on healthy hands and injury that goes beyond the technique category. There is a wealth of member created content on here about avoiding injury, so I think a sub category would be welcome by many.
My post is specific to the elbow, but may not be “golfer’s elbow” as I have gone to physical therapy for in the past. The pain flares up when I practice playing sixteenth note double time passages at 140 to 150 bpm. I posted a topic in the recent past about picking and technique suggestions related to picking double time jazz lines and I got excellent feedback. I’ll post some videos this week to demonstrate my technique further to isolate the issues. &Tom_Gilroy has some excellent posts that I would like to revive as well on this topic.
