Hi, my wife and I have been suffering from a cold. I have had it for 7 weeks and my wife for 5 weeks. Two days ago my wife began getting a sore throat again, like at the onset of the cold and now she has developed a very distinct rash and sites, a few with white bumps, like a canker sore, in a line from the back of her throat to the roof of her mouth and a bit on the insides of her cheeks. Any ideas?
