There are pains that can be explained: a fall, a blow, unusual exertion. But there are others that come for no apparent reason. A few twinges in the knee upon waking, a feeling of heaviness in the legs that doesn’t respond to rest, a dull ache in the bones that comes and goes. Pains that aren’t painful enough to warrant a trip to the doctor, but they don’t disappear completely either. And over time, these become silent companions of everyday life.
If this sounds familiar, your body might be trying to tell you something: that it’s lacking sunshine. Or, more precisely, vitamin D.
