My husband started having intense headaches that would radiate down his neck, shoulder, arm, and down around his chest. At the same time, his eyes would go blood shot, and he would get "tunnel vision" and he said he feels like he's in a "zone". After two trips to ER, two CAT scans, an MRI, blood work, etc... no one can say what the problem is for sure. It has been 4 weeks now and most of the painkillers that he takes makes him loopy, but doesn't take away the pain. His doc suggested Shingles. I've been reading about Shingles and it sounds like it only takes up to 2 weeks for the outbreak. Last night he was rubbing his head and noticed a spot on his head about 2 inches long and an inch wide, he said it doesn't itch or hurt to touch, and quite frankly, it doesn't look like chicken pox, cold sores or anything, just a welt. Has anyone heard of Shingles taking 4 weeks to come on, no pain relief even with MAJOR pain killers, and a WELT? Thanks all!
