<s>[INST] Hi , I had a lipo and abdominoplasty 2 months back . I am recovered from stitches but my abdomen around belly button has become very hard and darker with very less or no sensation. My PS open my incision to see if its hematoma but could not extract anything through vacuum. What it might be it s the size of football and hurts sometimes. What it could be? [/INST] Hi. Thanks for your query. Read the history and understood the problems. Lip and abdominoplasty is an extensive surgery of the abdominal wall where-in many blood vessels and nerves will be cut as a part of surgery. In your case the cutting or stretching of the nerves cause numbness around the belly button. The appearance of the hard and darker appearance can be due to an organized hematoma or Serbia, hence can not be aspirated as tried by your Doctor. I would advise you for a high resolution ultrasonography to see whether there is a subcutaneous collection or organization of the hematoma. Take Multivitamins for early recovery. Father treatment will be as per the clinical picture seen on actual physical findings and that found on ultrasonography of the abdominal wall and the abdomen </s>
