For the last few months i've been getting these shiny skintone bumps on my vaginal. Never inside of it. The bumps are bigger than pimples. They never pop bleed or puss. But is slightly painful. And they usuallly stay for about a week or two while getting smaller and then go away. Should i be worried?! Or could it be a result of something else? I have very sensitive skin with a lot of allergies and ecema.
