Q: I am a 29 years old unmarried man. Since the last 6 years I have some reddish black colour on my inner thighs. Initially there was some itching. Now there is no itching. But the colour is there. Also I have a dryness problem and my urine is yellowish in colour. I consulted a doctor before but he said that it was due to heat and told me to drink more water. Recently I have been getting chills during the summer season. What is my problem and how can I treat it?

A:Probably, you had tinea cruris, a fungal infection of the groin and that has healed with pigmentation. Other possibility is that there may be another infection called erythrasma, which can be treated very easily. Urine colour change may be due to dehydration, so you should drink plenty of water. Consult a dermatologist for further enquiries.
