Hi Dr Grief, my name is Terri, for the last ten days I have had a constant headache on the right side of my head, above my eye brow in my temple and around the back to my neck, it never goes away, feels like a constant pressure, my vision gets blurry at times and my ear feels blocked, when the head ache intensifies I get a fever and the shakes, been to the doctors she has prescribed me antibiotics for sinus problems the headache has not improve thank you
