my mother has a large cyst type ball at the entrance of her vagina. she is 70 years old, has never had any female issues that I know of other than perhaps a yeast infection when she was younger. There is no pain, itching, foul odor or redness. She does not have a fever and tells me she felt it 3 days ago. Her Dr s office is closed and I am wondering if I should take her to the ER or contact the Dr in the morning? Thank You
