Swollen Labia

Me and my hubs were having sex last night and it just didn't happen so he tried to finger me and I'm not sure what happened but he was going kind of fast and suddenly there was a *pop* noise and a sharp pain. My labia and vagina swelled up and we assumed he accidentally scratched me. But it's been 24 hrs and one side is still swollen and painfully tender. I can't go to the dr becuase the only one that accepts my insurance in town, is gone for vacation. Any advice on getting it down or getting relief? I thought about using my hemmoroid cream because it's never touched my bottom and it has a numbing agent in it. Has anything similar happened to you? I have the IUD and he was terrified that it got ripped out somehow but the strings feel fine, just a tiny bit longer.
