FTM AND my first hemorrhoid

Kimmie
So with my upcoming 1st visit to the midwife, I wanted to be more comfortable so I went to get a brazillion and they informed me that I have an external hemorrhoid. How the hell do you not notice that! Ive never had one before and it doesnt hurt so I guess thats why but it just baffled me. How do I get rid of it? Its not very big but I dont want it to get worse.
