Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain some amount of swelling of the lip after piercing seems to be due to inflammation secondary to
soft tissue injury and you need not to worry about it..
A small bump at the site of piercing seems to be due to
hematoma formation as there can be piercing of a small blood vessel while piercing..
White circle can be the area of inflammation only..
But in case if the area become painful and the lump has a white tip in the centre it can be a sign of infection and a then it can be a pus filled bump o an
abscess..
I would suggest you to take anti-inflammatory painkiller like
Ibuprofen..
Do cool compresses over the bump..
Avoid removing and re-wearing the lip ring or stud again and again..
You should also apply antiseptic ointment over it..
In case if it does not resolve in a week or the condition worsen consult a Physician and get evaluated..
Hope this information helps..
Thanks and regards.
