Brief Answer: IT IS MOSTLY A BARTHOLIN CYST. Detailed Answer: Hello, Thanks for writing to us on Healthcare Magic. According to your given information, I can assume that small painless lump near the opening of vagina is mostly suggestive of BARTHOLIN CYST which is located on posterior half of labium majus and usually one sided. It occurs due to blocking of bartholin duct by local inflammation or vaginal infection. Here, I suggest you to consult with gynecologist for proper pelvic examination to make a concrete diagnosis. TREATMENT: Small cyst usually does not require any course of treatment and it is better to leave alone. Genital hygiene maintenance is the key in such case. However, medium to large one needs small surgical incision and drainage of the collecting fluid which is called Marsupialisation. It is the procedure of choice and it can be done under local or general anesthesia. It is helpful to prevent abscess formation and future recurrence. In addition, you must prefer protected sexual intercourse, take adequate rest and daily sitz bath to reduce local discomfort. Oral antibiotic and analgesics can be given if there is pus collection. Kindly, visit to your doctor. Hope, I have answered your query. If you need any clarification, you can freely ask me. Wish your good health and take care yourself.
