My labia minora was swollen to more than twice it's normal size on the left side for over two months. I went to two different gynecologists and had multiple tests done and nothing bacterial or viral was found. I changed my diet, walking pattern, bought expensive probiotics, etc. and it only kept getting worse. Eventually I happened to find a piece of toilet paper wedged very high up in the vaginal entrance. It was the cheap industrial-grade kind that never rolls up or dissolves on its own. The swelling was a result of my vagina trying to push it out. After removing it the swelling has gradually decreased and I am hopeful that it will return to normal. I say all this to let everyone know that its a good idea to do a thorough search of your vagina to make sure there is nothing stuck in there. Looking back on the experience I feel a bit silly for not catching it sooner, but I didn't consider that there might be something foreign in there since two different gynecologists had already inspected the area and found nothing.
