Swollen vagina?

About a month ago I started getting discharge that smelt weird and I noticed my vagina was slightly swollen. We visited the doctor and he prescribed me cream for thrush. The symptoms persisted and the opening of my vagina became incredibly swollen, almost as though it now has flaps of skin covering it. We tried BV gel and that didn't work, the inside of my vagina is also slightly swollen. I couldn't visit the doctor because I've just had spine surgery 😂 Im recovering now and feel like I should see the doctor again, my discharge is now white, smells slightly off and there's a lot of it. Anyone know what this could be? It's driving me up the wall 🙃
