If your on treatment could be you're not drinking enough water. This is just a suggestion, but when you post give more information. If you have done that and you still have headaches, go see your Dr. Hope you feel better.
Sadly, I'm not clairvoyant. You simply haven't provided adequate background information related to your headaches or even if you're presently on treatment .
How about if you give that a try, even though it's tough to do if your head's throbbing.
