Suggest Remedy For Painful Bump On Left Lip Of Vagina

Hi I have just discovered a mosquito bite looking bump on my left lip on my vagina. It hurts a little and I have tried looking up to see what it is. But there are so many mixed answers and I don t know what one is the right one. I am 13 almost 14 I have not had sex before but I was raped for 5 years in my child hood. But I was told I was fine I don t have anything.
