<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi I am a 29yrs old female, I have a 4 months old baby. No relavant medical history. Present complain: I have noticed yesterday a marble sized swallow on my right labia minor on the inside red, quite painfull and seems to increase in size. What to you advise me to do about it! Thank you  <response>: Hello, I read carefully your query and understand your concern. Your symptoms seem to be related to Bartholdi cyst. I suggest soaking in a few inches of warm water either in a tub or site bath, four times a day for a few days may resolve even an infected Bartholdi cyst. Taking over-the-counter painkillers such as Tylenol may help with discomfort. If the symptoms continue, I suggest taking a cycle of antibiotics. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards! Chat Doctor.
