Hello, Thank you for posting to HCM. This is Dr. Papaqako answering your question. I m sorry for your problem. Yeast infections during pregnancy are more common than any other time in a woman’s life, especially during the second trimester of pregnancy. The inner thighs is a place where there is warm, moist and airless area of skin, that is a condition that help the fungi grow. There are various types and brands of antifungal creams that may help, for example, terbinafine, clotrimazole, econazole, ketoconazole, miconazole, and sulconazole. Apply the cream to the surrounding 4-6 cm of normal skin in addition to the rash. Apply for as long as advised. This varies between the different creams, so read the instructions carefully, usually 1 week after the skin lession has been cleared. Keep the area as much clean and dry as possible, as this will prevent the problem to be repeated. Hope this helps, Take care.
