I read some of the literature about RSI and this is a pretty common experience, which certainly does shake your faith in the medical establishment a bit. RSI is not even very rare.

I guess now people think I'm a crank; I posted here that I thought doctors just don't spend enough time with their patients and it's worrying and I was downvoted and mocked pretty hard.

Unfortunately I'm not confident that online resources would allow better decisions. I'm not convinced that patients would, by and large, do a much better job evaluating the quality of their doctors' care. The doctor who just gave patients antibiotics whenever they asked for them, whether or not it was appropriate, would probably be more popular in such a service than the doctor who took the time to understand their condition and explain that that wasn't an appopriate treatment.
