I doubt that your night of partying caused a leak. More likely, it just set you back to day one. Focal head aches are not uncommon. If anything is a problem, it is probably your anxiety.

Get a home blood pressure kit and take your blood pressure when your head aches are at their worst. Stress and anxiety can cause an increase in BP resulting in head aches. Tension head aches are the same as stress head aches.

If your BP is elevated, there are simple treatments for that.

Most of all, you need to relax. Your brain needs quiet rest.
