flag64 - I agree with you 100% on the "why", By all means, everyone should exhaust all possibilities. I did. In some cases, diabetics can keep the neuropathy under some degree of control or possibly stabilize the neuropathy by controlling blood sugars. I've always felt if one could find out the cause then perhaps a treatment could be offered. As you say, manage it. I spent 5 years trying to find the cause of my PN and I've come up empty handed until this past week when my neuro doc may have bumped into a cause. Perhaps. Still won't know for sure. It is a best guess sceneio. Many unknowns about PN and so much more to learn. Glad the THC and gaba is helping you. Ed
