I've had a fungal infection (yeast) over my ribs,upper chest, shoulders, back for atleast 4 months (on and off), I'm pretty sure it's tinea versicolor, I got a blood test and all, it came back normal if that helps. I'm 19, male and pale. At the start it was red and quite noticable, it subsided for abit and then sprung back up and now it's nearly clear, it's gone from a red to a light-tan, abit darker than my skin complexion, although I've noticed where it's healed (subsided for now), it's lighter than my normal skin colour, is this normal, how do I fix it?
