I have been having a headache for the past 3 days?

Keep a log / diary: Along with your other post (about leg pain), your symptoms suggest ill health. Unfortunately, with only 400 characters, I can't come to a diagnosis. (Again, use HealthTap Prime & talk to a physician). I suggest you take with you a diary of the headache / pain, its intensity, its location on your body, what triggers it, what makes it better, what makes it worse, what meds you take for it. Good luck
