What causes vaginal itching?
There are many different causes of vaginal itching, some of which are infectious, while others are not. Infectious causes are either bacterial, yeast or parasitic. For example, scabies is an infection that is caused by mites that burrow under the skin, sometimes including in the genital area. Scabies cause severe vaginal itching that is sometimes accompanied by a rash with blisters. The herpes simplex virus (HSV) can be sexually transmitted and its infection can result in vaginal itching - and often pain - that is accompanied by blisters around the genital area, redness and flu-like symptoms. Non-infectious causes of vaginal itching include contact dermatitis, which might be the result of using a harsh cleaning soap, vaginal douching, or wearing overly tight clothing. Another cause is psoriasis, which is an inflammatory skin condition that in the genital area can result in red scaly patches, itchiness and flaking of the skin.
