Hello. Thanks for writing to us at healthcaremagic I will keep your second possibility as my first i.e yeast Infection; itching and redness are part of yeats infection. My second possibility is Irritant contact dermatitis probably to aggressive cleansing (soaps and antiseptics) I would suggest that you apply an OTC topical plain antifungal e.g clotrimazole 1% cream, twice daily for a week. However, a combination antifungal+steroid would work better and provide faster symptomatic relief. An OTC oral antihistamine e,g cetrizine 10 mg once daily will provide you symptomatic relief from itching. If the condition does nt seem to improve within a few days Or worsens you must visit a specialist for a review. Regards
