I have already asked this question and I am asking this again with a bit detail. I have noticed white spots on my skin at my arms, shoulders, neck and chest from past few days. I forgot to take a shower immediately after taking a dip in the swimming people which was probably containing bleaching powder with water a couple of days ago. The white spots don't itch and are increasing a bit more each passing day. And I stay exposed to the sun very often without any sunscreen or any lotion. Kindly provide a possible cause of this problem and a remedy as well. I Don't get enough time to see a doctor, so write a prescription as well.
