I'm having red bumps on my vagina and at first I thought I t was ingrown hairs or razor bumps but I'm not sure and then it felt like I have a huge rash down there and I looked today and the upper right labia is swollen and when I try to use the bathroom as soon as the urine hits the swollen part the stinging is almost unbearable.. please help
