Hi ! Good morning. I am Dr Shareef answering your query. At the outset, I would advise you not to fiddle with this lump by yourself. You must seek the advice either of your family physician or from a general surgeon for a physical examination of your hard lump and then plan the management accordingly after a provisional diagnosis with investigations (like biopsy) if any. 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.
