Vaginal stinging - how to ease!!

So recently I’ve experienced a stinging/burning sensation around my vaginal opening. I had this same feeling about a week or two ago, which went away on its own, but now it is back again. I really don’t think it’s an STI, I think it might be either a reaction to the condoms/lube my partner and I use or some kind of vagina tear idk.

I’m planning on going to my gp to ask for advice on what to do. My question for now is: how can I ease this pain in the short term? I still have to get through work, house chores etc. in the meantime.
