I'm 15 years old and i have a lump on the inside of my labia or vagina flap, It looked like a pimple without a head at first, but it is very painful when i touch it or wipe it after going to the toilet. It doesn't hurt when I'm walking or sitting down or standing, but it hurts a lot more than a painful pimple does.
Could this just be a pimple developing in a weird area? Or could this be something else?
