Hi! Good evening. I am Dr Shareef answering your query. If I were your doctor I would have gone for an ultrasound and an MRI if needed t see in which plane exactly the swelling is located. The most likely diagnosis would be a femoral hernia, or an inguinal lymphadenitis or a simple sebaceous cyst. However these diagnosis is more of a physical examination diagnosis rather than by investigations. Therefore, I would advise you to please consult a general surgeon and get it reviewed by him for a definitive diagnosis and treatment. 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.
