I have shingles. I have had it more than a week. It is possible I caught it from a child who had chicken pox in the class I help with at school. I think it is more likely that I have it as I am stressed and run down. Am I infectious? How long do I have to stay out of school for? Am I confined to barracks? In the morning I am very stiff around the back and abdomen, is that due to shingles and what can I do as it is hard to get moving in a morning.
