I use Magnesium phosphorikum very often and very gladly. It is suitable for all kinds of pain and without chemicals. Simply dissolve 10 tablets in hot water and drink. It helps within a short time. The pain, especially headaches, is as good as gone. I am glad that my lactose intolerance means I don't have to do without it. It is also available lactose-free and gluten-free. As I also have a wheat intolerance
