Ok So I'm 16, I'm A Virgin, I Never Masturbate

Ok so I'm 16, I'm a virgin, I never masturbate but I did shave my vagina two days ago and today I wore a thing with my yoga pants and was sitting down in a movie theater for two hours and now I have this sore little lump almost to the top left of my clitoris and it's very uncomfortable and I went to squeeze and pus shot out of it and then it bled so I stopped. I also just finished being on my period yesterday so after I popped it I put Vaseline on it but I really want it to go away.
