Hello,
It is common to find some blister after using liquid nitrogen. In such a case, it is best to avoid messing up the blister as it will go away after a few days. In the meantime you can apply some Neosporin ointment if the blister breaks.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Hi, just thought of bumping this topic instead of making a new one as I have the same issue and was wondering if someone might know of an answer.
