Hi,Dear Thanks for the query to HCM virtual Clinic.
I studied your query with available details given in your query.
I understood your health concerns.
Cause of the painful and swollne lumps on labium-
From the facts given in your query,you seem to have-infected hairfollicles/
Boils,as your story goes by.
The lump on the pubic area near by confirms it being boil.
The chances of it being Barholins
Cyst are less in your case because of the weeks history when the first lump in right labium got bigger and was tender , not allowing you to sit even.
So Don't worry.Its not cancerous but is infective lump.
This would help you to plan treatment with your doctor, whom you should plan your visit urgently , before it complicates any more.
Don't Self-treat or medicate in your case as the case may go in to further complications.
Hope this reply would resolve your query and would help you to plan treatment with your doctor.
Hope this would relieve of your health concerns.
Welcome for any further query in this regard before final suggestions are given in your query.
Wishing you fast recovery..
Have a good day.
