Dampness and itchiness in the testicular area is more likely to be scrotal eczema. It is mainly an allergic reaction due to the stuffiness and humidity in this area and the fact that some people like to wear chemical fiber underwear. If vesicles, oozing, and redness occur, you need to apply mild, non-irritating topical medication for treatment. You can apply a 2% boric acid solution twice a day for 20 minutes, and then apply mupirocin ointment twice a day afterwards for anti-inflammatory and antiseptic treatment, because eczema can often be combined with Staphylococcus aureus infection. Oral loratadine capsules, 1 capsule once a day, combined with compound glycopyrrolate capsules, 2 capsules 3 times a day, are also needed for treatment. During the treatment period, avoid spicy and irritating foods, including raw onion, raw garlic and chili, and also need to avoid hairy products such as beef, mutton and seafood.
