I sweat a lot and work outside. A rash developed in my buttcrack and it burns. A lot. Most days, after getting home and showering, it no longer burns. And it only ever really starts to hurt after 4-5 hours of consecutive work/sweating. I m walking/running around a lot, so usually by 2 pm I notice it, then by four it hurts, and by 5 or 6 pm when I head home, it s nearly unbearable. I don t have insurance to see a doctor so any and all help is greatly appreciated. What can I do?
