To point #1: it’s been my experience that ergonomics and orthopedics are incredibly misunderstood by the tech industry at large, and in my personal experience, orthopedic doctors are often wrong in their diagnoses. One of many examples is the prevalence of Carpal Tunnel Syndrome in the world. It’s the most-common orthopedic surgery in the US, yet its success rate is thought to be around 90%. What would cause the surgery to fail? Technically it could be a botched surgery (eg scalpel cuts the median nerve), but that’s always known at the time of surgery because duh. Rather, the ~10% failure rate is mostly made of cases where the surgery went as expected, yet the nerve impingement symptoms persisted. There’s very little out there on the notion that these patients could simply have been misdiagnosed. If you feel tingling or numbness or burning in your fingers/hand, it could be caused really at any point between the spine and the hand. Typically nerve impingement of the hand occurs in the spine, thoracic outlet, cubital tunnel, forearm, or the carpal tunnel. The symptoms are more or less the same regardless, yet Docs seem to always implicate the carpal tunnel, even though there does not exist a reliable study that shows keyboard/mouse use is a risk factor for developing CTS.
