Are bites meant to get bigger and feel hot?

This is how it was at first:


This is how it is now after a day or so. I think it's bigger and feels hot 😮 whatever got me got me good and had a grand feast 😂:


I tried magnesium sulfate on it the cream I mean xD usually helps but nope. I even tried that Aztec healing clay I use too. I've just ended up with a very clean spot on my leg lmao 😂 . We can't get into our local doctors because it's over whelmed with patients and such either 🙁 .
