 [ Symptoms ] can hydrogen peroxide be used as a douche to control yeast [ Disease ] i am sorry to hear this headaches can go beyond annoying to actually disrupting your life if you are in otherwise good health you might try increasing your water intake dehydration can cause a chronic low level headache caffeine withdrawal also can cause a headache so if you drink coffee or other other caffeinated beverages regularly any reduction in your intake could give you a headache if your headache has any of the features of migraine i would suggest you see your health care provider for an evaluation for many people migraine is treatable if your headache is very severe or just will not go away i would again recommend you see your doctor a chronic headache can be a symptom of an underlying medical condition that can only be diagnosed by a physical examination i hope you feel better soon
