See a doctor. Can be many causes. Some are innocuous, such as a mild infection from shaving. Can be from infection (like cat's scratch fever). But may be more serious - hodgkin disease and non-hodgkin lymphoma can present in this fashion, metastatic melanoma or metastases from a skin cancer in the vulva can also present that way.
