Typically headaches accompany the onset of a cold, flu, and also strep throat.
Try taking a hot shower, going for a walk, or drinking lots of water. If your headache doesn’t subside for over a day and you’re noticing other symptoms such as a sore throat, it may be an initial sign of strep.
The headache portion of the illness is typically the easiest part of the ailment. Throat pain usually trumps all of the other side effects, but try taking an over the counter pain killer for the headache. A cold wash cloth over your neck and head may also help the pain subside.
