But “more study needed” in a big way! Beyond these scraps of evidence, for now there is only educated guessing and clinical experience.
Nothing’s ever simple and chronic pain least of all: it’s usually caused by a sinister stew of factors that eat away at people for many years. Trying to solve the problem by fixing one thing — if indeed vitamin D is even a problem — may be about as feasible as trying to fix a broken engine with just one tool. Vitamin D deficiency may contribute to a chronic pain disaster over time, but by the time you’re actually in trouble the problem may be much more complicated than just vitamin D deficiency.
That’s a bleak warning not to put too much hope into vitamin D. But there are still reasons for optimism! And the only thing worse than chronic pain with six causes is … seven causes. Obviously. Anything you can do to simplify the pain equation is a good idea, and you can certainly take vitamin D. (Just consult with a doctor first, please.) It’s cheap, safe, and effective, so it’s an ideal candidate for presumptive treatment: going ahead and treating based on the presumption of vitamin D deficiency even if it has not been established with blood tests. By all means do that too, of course! But if a lot of healthy people take this stuff “just in case,” it’s hardly radical for pain patients to give it a shot.
