Bump on labia minora

So I have a small bump on my labia minora, kind of in the "flap". It does hurt to the touch. I noticed it a few months ago it went away then came back recently. I think it's a type of cyst? Anyways I now have a swollen lymph node in my groin on the same side I have the bump. I don't know if it's related or not but now I'm worried. Minding you I'm 16, with no one to talk to about it.
