I am a 19 year old female. Around 5'9 and 145 lbs. I rarely get headaches, and when I do they're usually minor pain and fleeting. Last night I went to bed with a headache. I thought maybe I just needed to hydrate and get some rest. However, upon awaking this morning it had gotten worse into what I'm assuming is a migraine. I did have to go to work, which then proceeded to escalate the migraine. My head is throbbing, I can't focus, I'm sensitive to lights and sounds, I felt dizzy and lightheaded at work, and when I first got to work I felt like throwing up. I don't know anything about headaches or migraines but I'm hoping this isn't serious. I never drink alcohol or caffeinated drinks. I haven't been exercising much besides a little labor in the work environment. I sleep, drink water, eat normal meals. What is wrong with me?
