Hi! Good morning. I am Dr Shareef answering your query. Even though it requires a physical examnation of the groin area and the patient as a whole, from your history, it seems to be persistence of some kind of chronic infection in the area. If I were your doctor, after a physical examinaton, I would advise you for a complete blood count, ESR, VDRL test, Blood sugar test, an HIV and HbsAg test, gram staining and cuture sensitivity test of the discharge and a Mantoux test. If the reports of these investigations come out to be inconclusive, I would consider a biopsy of the tissue for a histopathology and the final line of management would depend on the reports. Till then, I would advise you not to fiddle with the lesion, and take proper care of it with regular dressings and a course of broad spectrum antibiotics with an anti inflammatory drug to be advised by the treating docotr for a possible symptomatic relief. 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
