There is really no such thing as a "tension" headache. You are suffering from migraine unfortunately. It may be caused by hormonal imbalance - it is "that time of the month" or even mid-cycle (ovulation)? You may need to look into getting some estradiol supplementation. My hormonal headaches are very hard to get rid of. I can take Advil with not much luck. Then I move on to Vicodin and try to sleep it off. It is hormonal though, it will usually return after the medication wears off. That is why estrogen replacement is usually the best bet.
