Some Black marks of burning on skin. Burning sensation is felt on the skin of testicles. Feels itching. I will not lie, Actually someone in bday party threw the diluted phenyl water or something like that Which cause me burning sensation ther, Than I had pore water and things were good. & also after that two days have passed and it caused me itching sometimes in between But today I wore yesterday's undergarment after bath due to emergency .. But now it started itching me in some parts not everywhere. And itching region looks like it has cracked skin. When applied with water it feels good. And calm for sometime. But after sometime walking & all it starts itching again. Don't know the thrown substance in bday party of 3 days before or today I had wear the same undergarment for few hours is that the reason?? And what medication can I take for that now??
