A Few Days Ago I Noticed A Slight Itchiness On

A few days ago I noticed a slight itchiness on my vagina but it went away for the most part. Two days ago I noticed a pain on my clitoris so I checked it out in a mirror and there’s a yellowish bump under the skin next to the clitoral hood. I have no idea what it is. I don’t want to squeeze it or touch it because I don’t want to make it worse but it’s causing me a lot of anxiety. Please help!
