My FH has shingles...oh joy!! He has been on meds for a few days now but at the end of every day his head hurts so bad, he lays in bed at 6 and sleeps because he cant get up it hurts so much. He is taking Valtrex for it, does anyone know if this could be from the med. I told him to call the doc. but why would he do that! grr i am tired of him being in so much pain!
