I have a dull pain left side waist that started approximately an hour ago. When I turn my body, the pain is one that if someone has grabbed my waist. I've been drinking water and took an anti acid tablet. So far, the pain is the same. Also, the past 3 days, my vagina is itchy. I've put cream to stop the itch. In addition, I did a self examination of my vagina. There are white spots inside. Are these symptoms serious enough that I need to go to the ER?
