<s>[INST] My son, who is nine months old and has had auto-immune thrombocytopenia (low platelets) since birth, fell three days ago by pushing his toy box around and hitting his mouth on the corner of it. He injured his top lip on the inside. The bleeding lasted about 7 minutes and then we got it to stop. Now he has something like a blood clot on the inside of his top lip where that thing is that connects your gums to your lip. He sucks on his hands to self soothe, and doing that makes it bleed a tiny bit. He doesn t have a fever and the clot doesn t seem to hurt him. He just gets irritable if I try to look at it. What should I do to make sure it heals correctly? [/INST] Thanks for your query, I have gone through your query.The lip injury might have resulted in the formation of the hematoma. This can happen secondary to thrombocytopenia. Nothing to be panic, you can apply cold over the hematoma(ice cubes). Do not disturb the area by touching it or moving it. It subsides in a week time. If it is not subsiding then consult a oral physician and get it evaluated.I hope my answer will help you, take care. </s>
