Painful Bump Down there

Hi all...

So I’ve been worried about a painful lump under the skin on the inside of my vag for 2 days..i just woke up with it 2 days ago and have been paranoid ever since.I know it can’t be an std and my family and friends think it’s an ingrown but it isn’t on the surface, it seems to be deeper than that. Anyways it is painful yet small. I was thinking the dull razor I used to shave could’ve cause this. Plus the fact that I spent the day after i shaved at an amusement park and was all sweaty getting on roller coasters.. Has anyone experienced anything like this? I plan on going to the doctor if it gets worse but was just wondering if this is something that’s happened to anyone else.
