I Noticed A Few Days Ago That I Have A

I noticed a few days ago that I have a lump under my skin on my mons pubis. It's only slightly painful if I touch it. There's no lump on the other side. It's pretty close to where my thigh comes together with my skin. There's also nothing on the outside of my skin, no irritation or redness or anything. I'm just really worried it's something bad.
