blisters

Hi,
I have recently started a new anti-fungal and had a strange reaction.

On my skin appeared at two location itchy blisters.

I stopped the anti-fungal and it went away, so it is clearly related.

Strange it seems because I normally don't have any skin symptoms at all.

It is a good sign to me, because I think a reaction is always better than no reaction.
It means it is working somehow.

Still I would interested in other people's opinion.

Are blisters even a candida symptom?
What else could it be?
