Chicken Pox?! Again??

IF you only had a very very mild case and did not develop immunity, then yes it is possible. It is rare, but it does happen. People who have had their immunity wiped clean by severe infections or things like chemo, are also vunerable to the same childhood diseases they already may have had, or were innoculated for. The only way to be sure is to see a doctor, so you know what I will say next, call for an appointment now. Good luck and don't scratch--it can cause scarring.
