Bumps on the vagina may be due to skin ailments, but are mostly due to sexually transmitted infections (STI). Other symptoms of STIs include pain, itchiness in or around vagina, abnormal vaginal discharge. However, some infected with STIs may remain asymptomatic. The Centers for Disease Control and Prevention states that STIs are hidden epidemics in the United States, mostly because people are afraid or embarrassed about it. For this reason, people end up not taking any treatment for it. STIs can affect people from all sections of society and have large impact on public health in general. If such infections are not treated properly, they can cause long-term health complications both in women and men.
