help me diagnose issues with my skin!!

hi,

out of nowhere my skin just went completely crazy, no history of anything like this.

note

1. I feel great
2. I have no itching or anything like that, in fact my partner had to tell me i had this
3. no fever, no symptoms at all
4. i have not been sick or have had any infections for long time

anyone got any ideas?

I am currently trying to see if it is related to

1. new protein powder i started consuming, this time the protein powder is flavourless, before that i used same brand but with banana flavour and i had no problems. i've switched to new protein powder right now, different brand, chocolate flavour, to see if there is anything there.
2. new place i started to live, tapwater, although my partner is not affected (switched to bottle water),
3. taking 3 scoops of creatine, although i've done it for over month and half
4. For long time I've only been taking one scoop of protein powder, but just a bit before this rash, I started taking 2 a day, so this could very well be related to protein intake.
