Re: New headaches
It is entirely possible your headaches could be caused by stress. Typical migraines last much longer than a couple minutes, they can go on for hours. That is why people use medications that can cause many side effects, to lessen the extent of hours long headaches. I do not mean to lessen the intensity of your headaches but if they only last a few minutes the side effects of migraine medication could be worse than the headaches.
If the headaches continue there is nothing wrong with asking your doctor about them, they can check and ensure there is no physical problem causing your headaches.
Try exercise and reducing your stress and see if your headaches do not lessen.
