spots

Hannah
Today my son has been grumpy and tired. When I changed his clothes before bed I noticed a few small red bumps on him. There were 3 on his thigh, and 2 on his arms none on his chest. He doesn't have a fever. Now I'm going to bed and I have the same spots on my chest, arms and scalp. They don't itch but they ache. Could this be chicken pox?
