Groin Cyst??? HELP

So for about 6 months now I have had this painful lump that sits under the elastic of my underwear on my bikini line in the front and it's painful to the touch and feels swollen. It's about the size of a nickel. Some times it goes away but it comes back every few weeks. I haven't been to the doctor yet because at first I didn't know what it was and I thought that it wouldn't come back once it went away... The only thing I have found online is that it could be some kind of cyst caused by a bacterial infection from shaving. I'm obviously going to see a doctor soon about it but I'm worried because it's more painful than normal and I'm wondering if any of you have experienced the same thing and have any home remedies to help subdue the pain until I go to the doctor?
