I think RSIs come from muscular imbalances, and tightness. It’s not just repeating the same motion, but that motion being almost uniquely how those muscles engage. You climb, so your forearm muscles are exercised on both sides. I’m guessing you also stretch a lot. But imagine you didn’t use the posterior muscles in your forearm, only the anterior. Eventually, the posterior muscles sort of seize in a tightened state because they can no longer counterbalance the anterior forearm muscles. Eventually, this could lead to nerve impingement, which creates the RSI. Tangentially, I know a lot of people who get pain between their shoulder blades from craning at the computer. What fixes that pain almost 100% of the time? Stretching your chest and anterior shoulders. It’s definitely possible that you have something else going on, but it’s insanely common for a person’s shoulders to roll forward, which puts immense stress on your back. Easy test: stand with your arms at your side, and your palms should be roughly parallel to your outer quad. If they’re turning in and pointing toward your knees (gorilla like), you need to stretch. In my opinion, there is a major gap in understanding of the muscular system in medicine. MDs don’t know how to approach pain except to numb it, or cut it out. Idk why, I just know that I’ve not personally seen useful results from MDs. PTs, ime, are usually excellent. But you schedule appointments with your MD, PTs only come in after an MD recommends it (at least in the US), which leads to the wrong solutions being tried a lot.
