My legs have some sort of reaction every time I go in the shower

Okay so this has been happening every time I come out of the shower for a while now and I was just wondering if it’s something that most people experience or if I should check with my doctor to see if I have a reaction. (A reaction to water? Probably not)

I’ve tried various different body washes (non perfume scented and others) and Ive also switched up my towels but my leg always ends up like this.

It’s got the look of a rash but it’s never really itchy so that’s also something that I’m not getting my head across. It usually lasts like this for half an hour and then it vanishes...?

So if someone would like to end my worry, it would be sooooo appreciated!! x
