Hi, I am 17 years old and just now found what I think is a cyst in the opening of my vagina (near what I think is my hymen...which is very thick). It is painful, and has been painful to wipe for the past few days or even touch down there, so I have not checked until now. I thought it might have just been a UTI, until I felt the lump. I really need help as I am very scared right now since I do not have health insurance and have been having a lot of problems in my tonsils and mouth (canker sores) in my mouth (I know this is not the place to receive help for that, it is just another symptom that I am getting around the same time as this lump inside my vagina). Also, the lump is moveable and kind of itchy, but not like a yeast infection. Please, if anyone can help, I would be so grateful.
Anyway, planned parenthood is FREE as I mentioned. They are in most cities--- even mid size ones. Check your city---- Las Vegas you have in your profile. They absolutely have clinics there such as Planned Parenthood where you can get a pelvic exam by a qualified doctor.
Here is a web page for you to look at that has all free and low cost clinics for woman's care in Las Vegas:

No one on the internet can tell you what it is for sure and if it will get better on its own. I wouldn't mess around and try to find a way to see a doctor. Your mom should make this a priority. good luck
