hi Seems like you have developed infection over the pierced area....Infection occuring after piercing is not that uncommon,,,,,so my advise is that,,,you should keep the area clean and dry as far as possible,,,use an antiseptic solution to clean it regularly...and apply an antibiotic cream,,,Do not apply any moisturising creams or lotions or oils over the affected area as it might increase the infection,,,if inspite of proper cleaning,, the lesion persists or increases , then you might have to remove the studd/ring put after piercing,,,and you might need a course of oral antibiotics and anti-inflammatory drugs ....So in that case, you might need to consult a dermatologist,,,, Hope it helps Dr Geetika Paul
