Itchy feet during lactation are recommended to be treated mainly with topical medication. It is recommended to first soak the feet in warm water to remove the necrotic keratin layer of the feet, and apply miconazole nitrate ointment or terbinafine hydrochloride cream locally. After applying the medication, it is recommended to use cling film to wrap the feet to facilitate better absorption of the medication and also relieve the dryness and cracking of the keratin layer of the feet. The cream needs to be used continuously for 5-7 days to effectively relieve the itchy feet caused by foot odor. As you are breastfeeding, it is advisable to wear disposable gloves when washing your feet or applying the medication to avoid direct contact with your hands to avoid infecting your baby with fungus and causing thrush. If the foot odor is serious and there are gray nails, local medication can only temporarily relieve the symptoms, and after weaning, it is recommended to take oral terbinafine hydrochloride tablets, which can completely treat the symptoms of the feet.
