I do get a bit of health anxiety so bare with me please!
Noticed these blue marks on my wall!! They weren't there yesterday! Was just a little concerned it's mold
But I don't know how as it's an indoor wall, in my bedroom which is very very warm and well heated etc..
I was rifling through my bedside cabinet earlier and chucking loads of things to the side to through out. I don't know whether I maybe rubbed against the wall with something?! Or else myself rubbed against the wall in the blue jeans I was wearing ( as you know the way sometimes you can get a blue stain from denim)
Call me down here as I do have health problems so always worry about the effect mold would have on me!
