Multitude of causes: You could have anything from low blood sugar to low blood pressure to stress to some form of headache syndrome or even cardiac or vascular problems. You could have metabolic, nutritional, or infectious causes as well. The point is you need to be examined by a doctor thoroughly who may wish to order blood work or other diagnostic tests. All the best.
