What I found to relieve pain that did work was a leaf powder akin to the coffee plant called Kratom. It's been used for generations in the east where it is prolific. That did relieve pain and had positive mood enhancement without making you nuts and, it is available at your favorite head shop, gas station, etc...probably soon to be put on the no-no list in many states.
But unfortunately, like any pain reliever, it loses it efficacy as your body adapts. By that time it becomes a habit like cigarettes if you let it.
