Chicken Pox?

The weekend we were at my parents house Ryver woke up Sunday morning and was scratching his head behind his ear. The way he scratched looked like a dog scratching fleas. I looked at his head fearing maybe he had lice or something. No crawling bugs but he had some red spots behind his ear. Didn't think a whole lot about it. We went to church, Ryver went to nursery, and we came home. I changed his diaper and there were more red dots. I wasn't terribly alarmed yet because he's always had sensitive skin and gets random spots and dots. The longer the day went on the bigger and worse these red spots got. By this time I'm starting to feel really bad about taking him to nursery. We are all thinking he had chicken pox. We drove home to Rigby and he started getting them around his hair line. I then start thinking that maybe it's an allergic reaction to his medicine he's been on for bronchitis and tonsillitis. No way he's been on it for almost 10 days. Put him to bed, and got up the next morning early and peeked at him and o my.....he had them all over his face. The spots looked like they were trying to blister but I just wasn't convinced they were chicken pox. I called the doctor's office and explained my situation. I know that there is nothing that can be done for chicken pox but if Ryver doesn't have them he needs help. He looked so terrible. They were all over his face and back, diaper area. He was scratching them and then were starting to bleed. I'd been giving him benadryl and rubbed the the anti-itch lotion on. And the verdict was.......allergic reaction to the Augmentin. They gave him steroids to take which was liquid and he was not impressed. But after only 2 doses and benadryl treatment he was cured. So thankful for moderation medicine, I think. One medicine gave him the problem but the other cured him. Always pro's and con's. As you can see the Cinderella sticker. That's the sticker he picked at the doctor's office. Then he plastered it on his wall, at eye level, with his pillow in bed. What am I going to do with this kid!
