<s>[INST] 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? [/INST] 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 clotrimazole/clobetasol/gentamicin 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! </s>
