I have a hard lump above my belly button that is tender and a little warm. I had a laparoscopic tubal ligation a week ago. Help?!

Maybe a suture but. Belly-button (umbilical) pain may originate locally due to infection or herniation, or be "referred" from another abdominal location like the appendix. Signs/symptoms of concern include: local redness &drainage, umbilical bulging that can't be reduced with gentle pressure, fever, vomiting, change in bowels, generalized abdominal tenderness (suggests peritonitis), worsening pain. Get checked pls.
