[|Human|] I found a pea sized lump on our 2 year old sons abdomen above the navel. Our pediatrician. Said it was a hematoma from an minor injury. That was 2 weeks ago. It is now visible and the size of a Lima bean. Should I take him back to the dr. He was one month and a week premature.
[|AI|]  Hi ! Good morning. I am Chat Doctor answering your query. If there is a history of trauma at this site, it could be a hematoma. Otherwise, it could be a small era umbilical hernia as well. However, this could be diagnosed by a clinical examination by your treating doctor. A hematoma would resolve of its own in three to four weeks time, whereas a hernia won't, and this could come and go at intervals. I hope this information would help you in discussing with your family physician/treating doctor in further management of your sons' problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor.
