DD complaining that her tummy buttons sore. It looks fine, not red or anything, but she is not herself. Went to docs yesterday, he spotted 2 new spots on her back and said chickenpox. But spots havent developed into pox, besides which she had it in the summer. Can you get chickenpox twice? Any ideas on he sore tummy button? (oh and wees and poos all normal). hope you can help.
