ah, hot water... stupid me always tried with a lighter, looking like a junkie and worried about burning myself.
not much to add, but that heat really works, as it breaks down the proteins that cause the infection/itching
Doesn’t have to be coffee of course - just get a spoon from hot (not boiling) water. It should be at the temperature where you can juuust stand to have it on your skin. Press and repeat as needed.
It will feel intense - even intensely itchy - for a couple of seconds, then….relief!
