What should i do if i've been experiencing very severe head pains. please help! ?

Headache: If you have tried all over the counterpain medications, you might consider a magnesium supplement, then see your doctor. You might need a daily medication like topamax (topiramate) or Propranolol to keep the headaches away. You can also find out if your headaches are coming from tension, dehydration, lack of sleep/poor sleep, skipping meals, stress, sleep apnea/snoring, or chronic sinus problems.
