Unknown lump cause, help- TMI question

So I noticed some aching in my pubic region, and thought I'd see if there was a cut or something, well I had a look but can't see anything, not even a zit or blister, however it's very sore to touch and I can feel a pea-sized lump in my labia minora underneath the skin. 
It doesn't seem to move but I don't want to try as it could make the pain worse. 
Could it be a bartholins cyst? It's driving me insane.
Oh and I'm 19YO
And only on the bar.
Please help, I'm kinda freeking out, and my doctor is 6hrs away and I have anxieties over seeing new ones. 
Thanks in advance
