<s>[INST] my son (3 1/2) jumped lost balance and hit his cheek at the corner of his lip on a bench. a day after he s still alittle swollen, bruised with a lump where the bruising is. should i call the dr or will it heal on its own? He s eating,talking and acting normal [/INST] Hi,It seems that there might be having some blood collection over the part leading to swelling and bruise.Nothing to worry, apply ice pack for 2-3 days and swelling and bruise will be subsided.Ok and take care. </s>
