Hi my 8 month old son has this on his testicles. Its red in colour, round circle, and raised bumps. I only use suda cream and johnsons powder on him which i stopped using both for over a week and only used plain cooled water but it's still there. Its not bothering him in the slightest. His testicles are normol to the touch and look no swelling. I only use pampers nappies as other brands do not agree with his skin very well. He has one same spot above his testicles. His nappie is correct fit. Any idea what this could be?? Thanks for replies in advance
