Hard lumps on the vulva can be caused by a variety of factors, including inflammation of the vulva, which can lead to vasodilatation and the presence of hard lumps on the vulva. In this case, you can go to the drugstore and buy a lotion, such as gynecological cleansing or cleansing, and use 1:10 water to take a sitz bath in the basin. Disinfect the hard lumps with iodophor or complex iodine, then apply a little erythromycin ointment and observe for 3-7 days. If the vulva has been irritated by secretions for a long time, this is when inflammation of the follicles is present. This can also be sterilized with povidone-iodine or complex iodine, and then erythromycin ointment can be applied, and the condition will improve in 3-7 days. When there is vaginal secretion inflammation stimulation, this will cause the vulva growth of cystic masses, such a situation, to exclude the occurrence of vestibular cysts. You need to go to the gynecology department of the hospital and undergo the corresponding examination to confirm whether it is a vestibular cyst or not. If so, oral anti-inflammatory drugs or surgical treatment is necessary.
