What an odd thing to say…!

Though I got a bit carried away a few nights ago and have a burn mark on my leg now

Hahahahaha

This, but I use the hottest water I can stand under the tap and go a few times.

The way this works is because the reason a mosquito bite is itchy is due to an enzyme in mosquito saliva which locally numbs an area when a mosquito bites you. Once the mosquito saliva enzyme starts wearing off, it registers as itchiness until the enzyme is completely gone. So, using heat to denature the enzyme, making it impossible to do it’s job, makes the itching go away.
