Hello dear,my name is dr,Dorina Gurabardhi.I understand your concern.
This rash is almost certainly
tinea cruris.
It is very common and nothing to worry about.
It can be treated by a number of over-the-counter creams, including
-
Canesten hydrocortisone (the hydrocortisone helps the itching),
-Daktarin cream or
-
Lamisil cream
Some advices that I can give to you are:
-After showering, make sure you dry the area carefully.
- Using some talcum powder after you have applied the cream may help.
-Wearing boxer shorts is better than Y-fronts.
Hope my answer was helpful,if you have any other question I will be glad to answer,thanks!
