Hi,
As one who does not take medication for pain there can be more complex reasons than just not wanting to take medication. For myself anything but opioid medication causes more damage than it cures so I'm stuck with the likes of codine and have no wish to become addicted. Believe me if addiction wasn't an issue I'd be taking medication rather than sucking up the pain associated with Autonomic polyneuropathy. With ANS a rule of thumb is to do what ever it takes to manage the symptoms, as you said there is no cure but there is also no treatment know either, just playing with the symptoms is all that can be managed.
Cheers
