Extreme head throbbing headache with sinus pain?!?!?

I’ve had this before, i woke up in the middle of the night with throbbing head pain i could barely even stand up without feeling nauseous. i went to the emergency room and they said that my sinuses were really inflamed and they gave me an antibiotic. it went away within a couple days. i have no idea what is causing my headaches and sinus pain i mean sometimes i have pressure in my sinuses and headaches but NO CONGESTION and i am so confused. anyone help?

Make sure you finish the antibiotic coarse if it doesn't go away by the end see your doctor. The worst thing you can do is not finish the antibiotic that's how super bugs are made and are extremely hard to kill
