Hello,
Increased size of the labia overnight is commonly caused due to some hurt, trauma, insect bite, injury due to friction or rough sex, ingrown hair and swelling / infection, BV infection, cysts (Bartholin cyst, etc.),
allergic reaction to ornaments worn on the private parts. You are suggested to take care of the hygiene of your private parts. If the inflammation is due to allergic reaction, you can take antihistamines at bed time, one SOS.
Take
acetaminophen or
Combiflam, one SOS when pain. Do not touch or squeeze. You can take hot or cold compress to ease the pain. Get clinically examined by a gynae to detect if it is
Bartholin cysts, ingrown hair swelling, STI, etc. You will be treated (conservative treatment,
drainage or surgery) accordingly. Your treating doctor will tell you to do STD tests to stay on the safer side. If reports are positive you will be treated with antibiotics / antivirals.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
