I too have had positive experience switching layouts for RSI (cubital tunnel specifically). While I am a bit skeptical on some of the more subtle claims by ergonomic enthusiasts, simply being more intentful around wrist posture seems to do me wonders. It may be more of a case where engaging in the niche is serving some broader truth, but I too directly associate my related journey to funny looking keyboards!

FWIW, all a doctor did for me was affirm my self-diagnosis and life-style adjustments. Surgery in this area looked quite grim on my last purview so I am not sure a doctor would serve much for most in this regard.
