Dear Concerned.,
Thanks for writing to us.
There are a few questions that needs to be answered.,
(a) Have you developed fever?(b)Is there
redness around the Belly Button? (c)Is the area very tender to touch?(d) do you feel local rise in temperature when you touch the belly botton?
If the answer to the above questions is yes, then in all probabality you have developed infection in the area introduced by piercing .In all probabality a subcutaneously localised infection.
In addition to baseline investigations Blood/urine tests/get the pus also tested for microscopy and culture.
Meanwhile you may start Local cleaning and dressing of the area with an antisceptic cream such as
Povidone iodine//Empirical Oral Antibiotics(after food)/NSAIDS(after food).
Then on receiving reports, start on a definitive treatment as per the indications in the lab tests reports.
Wishing you a speedy recovery.,
