My pool has a filtration system, and the clean, filtered water is pumped back into the pool via water jet. I was swimming in the pool and I passed the water jet, and the water ended up spraying onto my labia. At first it hurt a little, since the water shoots out from a 3-inch hole with a lot of pressure. When I was changing, I noticed that my labia was swollen. I applied ice, which temporarily eased the swelling. It is not sore at all. Would it be normal for my labia to swell from being hit by the water jet? And for how long will it stay swollen? If anyone can help, thanks!
