<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a small lump in the crease between my leg and scrotum, closer to the scrotum and slightly unerneath. . . It is slightly sensitive to the touch, greasy that has a strange odor not found normally in that area.That area.seems particularly greasy. At times i scratch and pull hairs from the a near that area, and i have seen similar come and go. Ive had the habit of rubbing dead skin and scratching and pulling hairs from the crease for some time- usually when on the toilet. What are these bumps?  <response>: Hi, happy to help you on your health concern on part of Chat Doctor! In the present case of a swelling or lump in the crease between leg and scrotum, if I were your consulting physician, I would just think of only one and one possibility and that is an infected sebaceous cyst or epidermal inclusion cyst! And, also, there might be some super-added fungal infections too! Recurrent folliculitis is also possibly there... As per your description, it is grossly infected and moist; therefore try to keep the area Chat Doctor. If you are still worried, get some cytological or fungal scrapping test or microscopic examination for confirmation and apply local clotrimazoleclobetasolgentamicin creams for 1 month or revert to us. Hope you got your answer. Please feel free to write to us if any more queries. Wishing you the best health!
