Hi ! Good evening. I am Dr Shareef answering your query. This could be an abnormal scar otherwise known as keloid, which is causing the problem. Even though it needs a physical examination to diagnose it with certainty, I would suggest you not to scratch it though it might itch to prevent its spread. For the present you may go for an anti inflammatory, and an anti allergic drug, and take an appointment either with a general surgeon or a plastic surgeon for further management. 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. I wish you an early recovery. Dr Shareef.
