Itching of the lower body requires a gynecological examination to see if there are pubic lice and a white belt routine to see what type of vaginitis it is. If it is mycosis vaginalis, you can vaginally insert nifurtimox and topically wash with benzalkonium chloride or skin disease and topically apply clotrimazole ointment. If it is bacterial vaginosis or trichomoniasis, you can insert Ornidazole suppositories and take Ornidazole tablets orally, and do not drink alcohol while taking Ornidazole tablets. You should pay attention to hygiene, don’t wear too tight pants, and underwear should be washed in boiling water before wearing.
