Thanks for all these additional details.
I can understand your concern.
Well, it is not normal to have painful lump at vaginal lips.
This could be related with Inflammed Bartholin's glands.
If this was not painful, then I would not be worried.
Such, Bartholin's glands are found just behind and either side of the lips that surround the entrance to the vagina.
Sometime, ducts for this gland can get blocked, and can result in swollen and painful glands. It is a very common condition. This is not releated with cold/ flu.
This could also be inflamed due to sexually transmitted bacterial infections like Chlamydia, Gonorrhea. But as you said, both of you have tested as clean, So I would not be worried for STD.
You should soak the affected part in warm water several times a day for three or four days and take over-the-counter painkiller like Motrin. It can be taken twice a day. Usually with home measures, it would get resolve.
In case, symptoms doesn’t improve in next 3-4 days, then you may need antibiotics.
Having little white spots, around inside part of vaginal lips is normal. No need to worry for that. They are not due to any disease process. They are quite common and do not do any harm.These are probably retention cyst. No need to worry for such white spots.
