i was just browing thru the above messages and i figured i have a problem similar to yours....
man, even i have jock itch; left side. Its very severe and it has been there for a long time now, maybe like 5-6 months. It is only getting worse. My skin in that area has become kinda rough and dark (pigmented) due to constant scratching. I tried a lot of creams, none helped.
You have any good suggestion man?
You answer will be really appreciated.
