Lack of vitamin d can cause pain i back muscles ?and is there some medicine that can increase vitamim d in the body?

Take Vitamin D: Vit d deficiency is very common ; chronic back pain is a common symptom.The best way to increase d is exposure to mid-day sun on bare skin but in most of the us it is impossible to get adequate d from sun in fall ; winter.At that time the best option is to take vit d3; most adults need 5-8000 iu/day to achieve optimal levels.See http://bit.Ly/1ekkvkv ; http://bit.Ly/1dc7vna ; http://bit.Ly/1fnt3ox.
