Thanks for writing to us.
As per your history let me analyse the same and give you the probabalities,
A)If the raised bump has appeared after the piercing attached to pierced portion,it is a case if Implantation Dermoid
which can be removed by a minor Surgery under local anaesthesia.
B)If it is a bump with a smooth surface with a pointing and firm to press, it could be a non-infected Sebaceous Cyst
C)The black spot could be a simple mole which could be left as it is. If it is painful/increasing in size/any bleeding through that the it needs intervention.
Kindly consult a General Surgeon
for further Management please.
Wishing you a speedy recovery,
Dr Lt Cdr ASN Bhushan.
