Thanks for using Health Care Magic
I would be pleased to answer your question .
The Large pore could be a sinus
or a sebaceous cyst , or calcinosis cutis
( deposition of calcium) .
Inclusion cyst is another possibility or follicular cyst
You will need to get the pore on your skin probed with the help of a Dermatome by the Dermatologist
. They will examine the area and will cauterize it to remove it permanently .
Thanks and take care
