My 8 month old has spots that look like chicken pox but the doctor says they are not. What are they?

Prob another virus. Many viruses particularly in the summer can cause a rash that may look like chickenpox. There are no special treatments for them. Tylenol (acetaminophen) or Motrin and lots of fluids will make the baby feel better.
?????? At least that doc can look at it. There are a variety of viruses that produce blister like spots & an exam can often help sort out the proper label. However, without an exam the cause remains speculative.
