[|Human|] I have a hard, circular lump underneath my skin in the crease of my left leg near my pelvic area. It is about the size of the top section of my thumb. Recently, i have felt sensitivity when i urinate - it isnt pain or discomfort, but it just doesnt feel normal.
[|AI|]  Hello! Thank you for the query. It is hardly possible that the lump under the skin is related to urinary tract issue. In mentioned by you location, lymph node or benign skin lesion are most probable. The best way to find out what it is, is to have soft tissues' ultrasound of this area. In case of enlarged lymph node, biopsy should be done. Benign skin lesion can be removed with small incision. Sensitivity when urinating can be caused by urinary tract infection. Therefore, I suggest you to have also urinalysis done. Hope this will help. Regards.
