[|Human|] My 2 year old fell off her sister s back and landed on the area under the chin. She has a small very dark bruise on the right portion of her chin but more alarmingly she quickly developed a large knot under her chin. This happened two days ago and the knot hasn t gone away. It is very pronounced and distorts her lower chin (double-chin-like). The swelling seems to now cover a lot of the area under the chin and is firm (like a firm double chin) Should I see her doctor or should the swelling go down?
[|AI|]  Hi ! Good evening. I am Chat Doctor answering your query. From the history, it seems that she has got a hematoma formation which usually takes about 2- 3 weeks time to get absorbed unless it increases in its size. But she needs to be examined by your family physician/general surgeon of your area to rule out any chances of a submental infection, which could also give rise to similar findings and needs to be treated soon. So take care. I hope this information would help you in discussing with your family physician/treating doctor in further management of your 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. I wish you an early recovery. Chat Doctor.
