Help?! 💟

Okay so maybe 3 days ago i noticed that i had a small pea sized lump on the right side of my outer lips of my vagina, it was pretty much painless unless i applied too much pressure but it was really itchy. Over night it grew larger and became more and more painful. It's not really round it's kinda long like moving down my lip. I'm really stressing out on what it is because it really hurts and its quite hard. I don't know whether i should see a doctor or not. I'm also not sexually active. It's red and swollen and very painful now, even to sit or lie down i can still feel it throbbing. I've been trying to have as many hot baths as possible, and putting hot cloths on it, but there is still no sign of any form of liquid inside nor a head..  Any advice would help 💛 thank you!Â
