Grant,
One bad thing about starting on drugs is that, if they give you relief then you become complacent about trying to pursue actually healing your condition. There is the temptation to go back to life as usual.

If your symptoms are 'tolerable', whatever that is for you, then I urge you to continue pursuing a cause for your PN and attempt to reverse it, or at least manage it, with exercise, a healthy diet, stress management, supplements, and maybe certain foods that you find to help. And for me, a healthy diet does not mean switching from beef to chicken, or eating a smaller portion of pizza, it means eliminating animal products and loading up on fresh vegetables (especially leafy greens), fruits, legumes, and whole grains.

If you get to a point where you cannot function normally (school, work, etc.), you are just miserable, or your relationships are suffering, then I think it is time to get on some medications.

You have found a good group here, so just keep posting your thoughts and you're sure to get some good feedback. Good luck down there.
