Hi Akash.
Some time after I discovered my T1, I started to have darker colored areas of my torso and especially my back, and these areas were itchy, especially if I was playing sports and sweating.
The dermatologist diagnosed "Psoriasis versicolor", and gave me an antifungal medication called Diflucan, composed of Fluconazole, which took effect.
But every year at the beginning of the warm months I have to repeat the treatment.
I hope it can help you.
Hi
Andrea
