Is any of this happening?
Be seen today
Prompt advice is appropriate if an attempted removal leads to increasing pain, warmth, redness, swelling, pus, or fever.
These can be signs of infection.

Does any of this apply?
Book an appointment
Arrange a routine appointment if the bumps are persistent, numerous, or causing distress.
An assessment is also reasonable if you are unsure whether they are milia or want to discuss safe removal.
Seek routine medical advice when:
Milia develop repeatedly after skin injury or blistering
Many bumps appear over a short period
They form within a red or raised patch
A child has widespread cysts or other unusual skin changes
A bump bleeds, crusts, enlarges, or changes colour
The article also says
Milia are not an emergency.
Every sign above is quoted from the sofidex article on Milia. If you are not sure, err upward — it is always reasonable to be checked.
