My partner has been experiencing recurrent Bartholin gland cysts. The first episode occurred on the left side in February, which resolved with antibiotics. In April, she developed swelling on both sides and underwent incision and drainage. Now, in November, another lump has developed on the right side. The current swelling has persisted for seven days, although the pain has subsided. There is no visible pus, and she is currently taking antibiotics. We would like to understand why these cysts keep recurring and what would be the best long term treatment to prevent further recurrence. Please suggest the appropriate investigations and treatment options.
