does anyone know what this could be??

ryley

its discoloring in my body and ion like it at all. i’ve been to a doctor about this and a couple other things, they gave me some soap and it didn’t go away. i went like 3 years ago. i have no clue what it is but it’s starting to bother me because it’s spreading a little to my arm. it’s not just in the summer time. it’s year round. for now it’s only on my back and chest, now arms a bit.
