Headaches are not uncommon and most of the times they are mostly an annoyance and nothing serious. Take two Advil or Extra Strength Tylenol every 4 to 6 hours. Get plenty of rest. Do a gentle range of motion stretching with your neck, gently massage your neck and shoulders. Call Student Health Services if your headache follows a head injury, is accompanied by a stiff neck (an inability to flex your chin to your chest), and change in vision or level of consciousness, generalized weakness or loss of function in any extremity, or if your headache persists for more than 24 hours.
