A few days ago I started having itching, irritation, burning and curd-like discharge and I immediately thought I had a yeast infection. So I started taking AZO yeast. Then yesterday I noticed swelling inside my vagina. I think it's my urethra that is swollen but I'm not sure. If I use a mirror to see and open my labia, there is something swollen that is basically blocking the entire hole. I don't have the burning with urination any more, but still itchy and irritated. I don't like going to the doc out of modesty. Could this swelling be associated with a yeast infection, or something more serious?
