Hi ! Good evening. i am Dr Shareef answering your query. Yes ! You are possibly right in saying that the wound of ear piercing has got infected. If I were your doctor, I would have started an anti inflammatory, and a broad spectrum antibiotic for you followed by referral to the ENT specialist for a review of the deafness which you have developed recently. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
