[|Human|] Hi, may I answer your health queries right now ?  Please type your query here...I have a lump above my belly button after umbilical hernia surgery 3 months ago due to my last pregnancy.   The lump can be pushed in like a hernia but doesnt stay in. The Dr. said he didnt know what it was but could fix it with another surgery.  Im not sure I want to have surgery again.  Should I have some tests done first before I decide on surgery?
[|AI|]  Welcome to Chat Doctor .1. The history suggest recurrence of the umbilical hernia. Second possible cause could be infective collection in the post-operative site.2. Yes you have to undergo investigations before get operated.3. Firstly ultrasound abdomen and bulge / lesion - ultrasound will help to assess the defect, its content, weather there is any strangulation of bowel and so on.4. If it's a collection - ultrasound evaluate the nature of collection, its source and extensions.5. A CT computer tomography will be additional information, better evaluation of umbilical hernia.6. So undergo the tests and follow the treatment according to the findings. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
