I have a lump in my vagina?

I have been having an itch in my private parts for a few days now, but only from time to time. I didn't have any white discharge until this morning when I looked on the internet and saw that some of the symptoms were that I went to the bathroom and as luck would have it, I had some. It was really weird. I looked at what I had and at the level of the vagina I have a ball which is rather large. I know that I had one because I had its pains because when I went to the toilet while wiping I felt a small ball and pushed on it to know what it was and since then I have had pain.
