Hello,
The basic procedure to stop blistering is to douse the affected area under a cold running tap for 10 minutes ? did you do this?

I would advise you to leave the blister and if any more appear to go to Accident and Emergency unit at Hospital or to your GP.

You can get burn gel from local supermarkets e.g. Tesco, this may help sooth any burning pain you have.

If problems persist get it checked out

Hope your OK

If you want oozing puss everywhere i would advise you to leave it to heal or go to the doctor.
If you pop it, it will come back worse.
