Hello dear
Understand your concern.
It may be cyst that is common in vaginal area.
I think it is skene's duct cyst: It look like pimple near the
urethra.
It require no treatment.
But if associated with itching, redness and pain , it require
drainage and antibiotics
Following are the other cause of lump in vagina:
1. Blocked hair follicle
2. Blocked sweat gland
3. Fordyce cyst
4.
Molluscum contagium
5.
Bartholin cyst: rare
All this cyst are pain less and harmless generally.
Do not pop up , it causes infection and bleeding
But if it is very large and associated with pain, dysuria, fever, itching , redness and foul smelling
vaginal discharge.
Then
You should think about infection
And consult to doctor for drainage and take antibiotics.
Also maintain hygiene and keep the area dry.
Hope this may help you
Best regards
Dr. Sagar
