I have had these brown patches on either side of my groin for awhile now and they seem to be getting bigger very slowly. The condition has been around for probably around 6 months. They can be quite itchy at times and are very unattractive. The closest thing that I have been able to find that resembles it is something called "jock itch" and another called erythrasma. I should prolly see a Doctor but I am quite shy about this subject. Thanks for any help in advance.
