I have a skin disease, it appears circular and red. It pains and burns when it increases. I have been taking medicines from almost one year, skipping some days in between when I notice, that it's cured but whenever my periods date come closer, it comes again, sometimes white water is filled in the border of red circles. When it's cured, my skin colour becomes light at that particular part. This is viral and almost from my family has got this now. I have spent alot but nothing happened.
