<s>[INST] my 3 year old son smashed his finger a week ago, the nail turned white and started to raise up, he caught it on some laundry and is now crying in pain but wont let me put ice or a bandaid on it but its still attached what can i do for him and should i take him to the dr. [/INST] HIWell come to HCMI really appreciate your concern, such injury need to be examined clinically because fracture would be the matter of concern, and second blood circulation disturbances also need to be ruled out,  hope this information helps, take care and have a nice day. </s>
