Red swollen clitoris with bumps? Help?

Hi. For the past 4 days my clitoris has been red and swollen, painful to the touch. I recently discovered a small blister on it, so I assume that's the cause of the pain. But I've had a vaginal blister before and it went away after 3 days without problems. This one has persisted and has not been getting better. I examined myself a little bit more and I saw maybe 2 or 3 small bumps along my labia minora. They don't look like herpes-- they look like common blisters with no harsh border. I'm a virgin, so it's not an STI. It hurts when my clothes rub against it as I walk around and it itches sometimes throughout the day. The only way I get it to feel better is to sit with my legs wide open or put and ice pack on it. I don't know what it is.. help?
