Itching and pain in the vulva is clinically caused by either dermatitis or inflammation of the vagina. Skin inflammation such as eczema of the vulva or other clinical skin inflammation such as vulvar seborrheic dermatitis may cause itching of the vulva, and scratching and breaking of the skin may cause local pain. Vaginal inflammation such as Candida infection, trichomonas infection, mycoplasma infection, chlamydia infection, bacterial vaginosis and pseudomonas infection can cause inflammatory reaction to the vulva, resulting in painful and itchy symptoms. It is recommended that if you have painful and itchy vulva, you should go to the hospital to have a checkup to see if there are any rash-like changes in the local skin of the vulva, and it is also recommended to have a routine laboratory test of the white belt to give treatment according to the results.
