@bunnybear What an unpleasant disease to get! I’m so sorry. According to Mayo Clinic, you are contagious until your blisters scab over.
“Chickenpox can be dangerous for some people. Until your shingles blisters scab over, you are contagious. Avoid physical contact with anyone who hasn't yet had chickenpox or the chickenpox vaccine. That includes people with weakened immune systems, pregnant women and newborns.”
I would suggest a serious talk with your doctor.do you think your plans can be changed to another time, if necessary?
