The swollen labia may be due to cidnada overgrowth (yeast infection). You do not need to have intercourse to get it. If it has been there for a long time (sometimes it can be in a dormant state, causing almost no signs) it may make your labia swollen, itchy and red. Acidophillous is a great way to prevent yeast infections, but i wouldn’t bet on them if your infection has gone a little too far. Does it burn or sting when you wash there? Do you have more abundant discharge, even if it has not changed color/texture? If you do, it may be thrush caused by candidiasis. The treatment here would be applying a cream inside the affected area (like Monistat or Lotrimin), but let the ob/gyn diagnose you.About your MD well, i’ve seen doctors give medical attention to people who won’t just lack photo id, but cannot pay also. There are hundreds and hundreds of really well prepared doctors, but only a handful who will treat you like a person, i’d stick to those and forget about the ones who think even a word of sympathy is payable.In the meantime (your appointment is tomorrow, right?) go buy some natural, color-free, additive-free (best if organic) yogurt and apply on the affected area. It feels more soothing if it’s cold. Let it sit for about 15 min and wash with water only. Dry thoroughly. If the itching is absolutely killing you, take some Benadryl to help ease the reaction on your skin.
