Thanks for the query.
According to your description, the bumps you noticed could be blocked hair follicles.
These can cause folliculitis
If they increase in size, there is possibility of accumulation of pus in them.
So, if the pain persists, once consult gynecologist and get examined.
You may need systemic antibiotics along with local cream you are using.
Sitz bath can help in decreasing the symptoms.
Better to avoid harsh hair removal
creams on sensitive areas.
