Hello. Welcome to ask the doctor. I understand your concern.
Although it is said that once chicken pox occurs, one can never get it again. But practically its not true. I have seen many patients with repeated episode of chicken pox even after shingles.
So the rule is not strict.
I hope I am able to solve your query.
If you have any further query, you may ask us.
