Is any of this happening?
Be seen today
Seek a prompt medical assessment if a spot:
Is new and looks different from your other marks
Changes in size, shape, color, or height
Develops an uneven border or several colors
Becomes painful, itchy, crusted, or repeatedly bleeds
Forms a sore that does not heal
Returns or changes after treatment
These changes do not necessarily mean skin cancer, but they should be examined rather than treated at home.
After a cosmetic procedure, contact the treating service promptly for increasing redness, warmth, swelling, pus, worsening pain, or fever.

Does any of this apply?
Book an appointment
Arrange a routine appointment if you are unsure whether a mark is a liver spot, want advice about removal, or have many pigmented spots that are difficult to monitor.
The article also says
A liver spot is not an emergency.
Every sign above is quoted from the sofidex article on Liver spots. If you are not sure, err upward — it is always reasonable to be checked.
