My scrotum seems to be swollen and turns into a huge sac every morning but gets better as the day goes on, usually at night. I feel like drinking a lot of water helps it relax and drop again. Warm showers make it better too. I usually go to sleep with a relaxed scrotum, but when I wake up, it is swollen again. There is no pain of any kind, but sometimes there is some discomfort. Does anyone know what this is?
