Red spots with yellowing on sensitive areas may indicate an infection or irritation, such as folliculitis or a yeast infection. These symptoms can arise from various factors, including friction, poor hygiene, or skin conditions. To help soothe the area, maintain good hygiene and avoid irritants. Over-the-counter creams may offer relief, but it is essential to monitor the condition. If these signs persist or worsen, I strongly recommend consulting a dermatologist for an accurate diagnosis and appropriate treatment.
