Hi
I'm going out on a limb here and after the horse has bolted.

At the first instance - first aid copious cool gentle running water to take the heat out of the burn before blistering. FIRST AID for far longer than you might think to get the heat from the deeper layers of skin IS CRITICAL hence lessening the degree of the burn & consequential blistering.

Soap & water is not the answer just lots of cool clear running water NEVER anything that contains oil.....as soap does as Tayla says you are continuing your cooking.

No ice - just cool clean running water in copious quantities - when you think it is cool - keep going.

Sorry if that treads on toes but it is the only way & the results should be better lessening the long term consequences &/c.
Best regards for a full recovery.
