Hi. My 7 yr old had chicken pox really badly over the last 2 weeks. His brother (5) has one spot under his arm (classic place) looks like chicken pox, has blister. But its the only one and it appeared on Saturday. I must admit when people tell you their child only got one spot, i would think hmmmm dont think thats chicken pox.......but no idea now! Anyone any ideas??? Making it difficult to know about going to school. x
