I can attest to that. I tried microsoft ergonomic keyboards, logitech keboards but they didn't help then i found kinesis freestyle split keyboard and since then almost all the issues are gone. prior to switching to kinesis, i also switched from kwerty to dvorak, It helped but not that much. I used to have issues with my right hand due mouse usage, so i switched from right to left hand because i am right handed and unconsciously i was using it way more then my left. you do need to complement the change with upperbody stretching.
