Are you on birth control? Hormonal birth controls can put you at a higher risk for yeast infection, which might be explaining the swollen labia?
Are you experiencing any itchiness? If so, it might be a good idea to call your OB/GYN or your regular doctor and explain your symptoms and maybe they can call in a script for you.
Hope this helps!
Hello,
The symptoms are suggestive of allergic contact dermatitis or friction rub. Use mild soaps, wear cotton clothes and take some antihistaminic like Benadryl or Claritin. Also consult a dermatologist as you may need topical as well as oral steroids.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
