Hello. As of late I have been getting terrible headaches. But not like any headache I've had in the past. The difference is it is like a stinging type of pain not like a swell pain. The pain hurts above my left eye on forehead in the top left of my head a little more than half way back. Sometimes it even hurts into my ear. Also when I blow my nose (which I don't do often) it feels raw and painful, blood is absent more than present. Sometimes it also hurts into my teeth. I went to my Dr and he check for ear infection which I didn't have and gave me antibiotics. Still the pain persists and it's fairly constant at 3-4 times a day. It first started at 1 time a day and was quick. Now it's 3-4 and lasts about 10-20 mins if not longer. What could this be?
