Hi,
Thanks for posting in HCM.
I understand your concern.
The lump what you are having inside vagina appears to be '
Bartholin cyst'.
Since it not painful, it appears that it is not infected.
You can overcome it by doing the following:
1. Take anti-inflammatory medication Tablet.
Ibuprofen twice a day after food.
2. Rinse the area with mild antiseptic solution like
Savlon twice daily.
3. Take sitz bath everyday for about a week by which time the swelling should subside.
4. Use vaginal pH balancing solution like 'v wash' regularly.
5. Abstain from sexual activities till the symptoms subside completely.
Keep good personal hygiene. Gradually the swelling should subside and should be back to normal.
Hope the information provided would be helpful.
All the best.
