Is any of this happening?
Be seen today
Seek same-day medical advice if the skin becomes rapidly more painful, hot, swollen, or red, or if redness spreads away from the bump.
Pus, red streaks, fever, or feeling generally unwell can also suggest a skin infection needing prompt assessment.
Redness may be less obvious on darker skin, so pay attention to warmth, swelling, tenderness, and skin colour changes.
Get urgent help if bumps appear near the eye with significant swelling, eye pain, or vision changes.

Does any of this apply?
Book an appointment
Book a routine appointment if a papule or group of papules:
Lasts for several weeks without improving
Keeps returning or continues to spread
Is very itchy, painful, or interfering with sleep
Bleeds, forms repeated crusts, changes shape, or does not heal
Appeared after starting a new medicine
Is accompanied by unexplained hair, nail, or mouth changes
Every sign above is quoted from the sofidex article on Papule. If you are not sure, err upward — it is always reasonable to be checked.
