Hi,
Thanks for posting in HCM.
I understand your concern.
From your description, it appears that you could be having fungal (yeast) infection in the genital area.
You can do the following to overcome it.
1. Clean the area with mild antiseptic solution like
Savlon twice daily.
2. Following drying, apply
Clotrimazole skin cream over the lesions.
3. Take Tablet.
Levocetirizine once a day if you have itching sensation.
4. Apply moisturizer cream or lotion over the lesion at bedtime.
5. Wear loose undergarments to provide proper ventilation and avoid friction.
6. Abstain from sexual activities till the lesion heals completely.
Hope the information provided would be helpful.
All the best.
