help I have a bump

I have a bump on my outer labia that really hurts and at first I thought it was an ingrown hair so I tried to get rid of it and that didn't work only hurt a lot so I thought maybe it was a pimple or something and poked it a little with a razor but that wasn't it. it hurts a lot when I squeeze it and it gets irritated when my clothes rub up on it... I don't know what it is and what to do. 16yrs and getting to the doctor over something on my little lady is hard.
