After having a vomiting bug on thursday and Friday last week, I developed a really itchy rash on the left of my back on Sunday evening which had got bigger by this morning. My GP says its shingles. Has anyone had this? Any experience of whether the rash gets worse before it gets better? My GP gave me acyclovir for a week. I'm worried as I have a toddler (who has had chicken pox- but only a mild version when she was 1 yr old) and a 4 week old baby who has never had chicken pox. I know you can catch chicken pox from someone who has shingles if you've never had it before. Help! Also what other symptoms did you have with shingles?
