Vaginal itching is a relatively common symptom that, in most cases, is a sign of skin irritation or an infection. This symptoms may be a sign of a more serious infection like a yeast infection, a sexually transmitted infection or cancer. 

When itching is caused by an allergic reaction or irritation, it is mostly felt externally and is caused by friction of synthetic-fabric underwear. The use of synthetic underwear or jeans can cause more irritation and worsen the itching.

When the itching is internal, it may be caused by the presence of fungi or bacteria, which often provoke other symptoms like local swelling and discharge.
