You forgot to mention the problem. Please send photos using online consult option for proper examination diagnosis and treatment advice

Fungal infection.. Also called jock itch, when occurs in groin.. Usually fungal infection is common in moist areas of body like skin folds..It's mostly circular or round in appearance.. May be red or black in colour.. Treatment depending on the type and severity.. Avoid sharing clothes, towels and soap; sweating also increases it..As it has to be differentiated from eczema, bacterial and viral infection, doctor need to see to confirm the diagnosis..So, meet me in my clinic or do direct online consultation by sending photos for detailed information and medicine for treatment.

Without examination of the skin condition and knowing the extent of involvement.. along with this more information on ongoing medication or history of previous/current skin/systemic illness it is not possible to comment on the treatment that would suit you best. Please get the problem checked thoroughly by visiting a qualified dermatologist or you can send images online through private online consult for a better assessment of the problem. Hope this is helpful
