those symptoms are so general why the fuck would your first response be brain tumor? if you had pain maybe? also for the record a hang over is an electrolyte imbalance so if you drink something like gatorade it will help alot, the imbalance actually causes inflamation in the brain aswell so if you take an anti inflamatory like iburprofen it can aid with headaches. if it lasts for awhile i would have said see a doctor but who trusts them after crying wolf so many times
