From the description, this bump/lump like structure was present on one side and close to the entrance of the vagina. That could be either a Bartholin's cyst
or a normal cyst.
The fact that you were able to pop it supports that diagnosis. But we will have to make sure either way.
Please keep the area clean and dry as it can result in a re-infection. Please visit a doctor if you do experience a re-infection or worsening of your condition. Also warm sitz baths and warm compresses through the day to the affected region can help to a certain extent.
Hope this helps.
