Thank you for the info. but the small hard bump is at the virgina entrance inside. I have been taking a variety of vitamins lately and thought maybe it could have cause the bump. I am 58 years old and not sexually active, been celibit for many years.
I get these from time to time. Your labia has hair folicals that can become inflamed or even infected. It is not uncommon for a pocket of pus to form. The remedy is warm sitz baths or warm compresses to draw out the infection. If that doesn't work, your gyn can lance it for you.
It is probably an ingrown hair and will have to come to a head before it will go away.
