I have this rash that s been reoccurring for about a year now. It falls on my butt almost close to my butt crack. It just appears, gets itchy, try as much not to itch though. It doesn t hurt nor show signs of appearing, i just see it there. This is like the 4th time it s come. I use antifungal creams and it goes in like 3,4 days like it came. Just want to know what it is so can get the right treatment. It s not blister like lumpy like small blisters, dry though
