I've been sick for 2 days now woth fever and headaches that wont go away. What should I take?

Fever & headache. As long as the fever is not high (persistently > 102), and if it has only been 2 days, i would just take Ibuprofen (otc), 3 tabs 3 times a day as this is probably a viral process that will go away by itself. I would wait up to a week for low-grade fever and mild to moderate headache to go away on its own. If the fever is high, or if the headache is unusually severe, you should see a doctor.
Fever/headaches. Seek medical attention. These symptoms may be due to an infection including meningitis.
