Hi,
Thanks for posting in HCM.
I have read your description and understand your concern.
What problem you could be having inside vagina be due to presence of 'Bartholin's cyst'. Since it is accompanied by certain amount of smell, it could be infected.
Kindly do the following to overcome it.
1. Clean the area with mild antiseptic solution like Povidine-
iodine solution thrice daily.
2. Take anti-inflammatory
analgesic medication like
Ibuprofen after food.
3. Take a course of antibiotics containing Amoxacillin and Clavulenic acid.
4. Take warm Sitz bath twice daily.
5. Abstain from sexual activities till the lesions heal completely.
It should start to subside by doing above measures by 3 to 5 days.
In case the lump recurs or does not subside, you may have to undergo a procedure called 'marsupialization'. Kindly consult Gynaecologist in this regard for evaluation and management.
Hope the information provided would be helpful.
All the best.
