<s>[INST] my 2 year old son was hit on the top of his head with a toy over 2 hours ago and it pierced his skin, it was bleeding for a few minutes then stopped but there is a lump.  when i was putting him to bed (30 mins ago) he was complaining that his head was sore when he lay down, he wasnt touching the injured area, is this normal? the only way he could fall asleep was upright in my arms.  he said he was feeling sick but he didnt vomit and now he is asleep.  should I take him to the hospital or will he be ok? [/INST] He will be OK if u don't take to a doctor also.but if there are any signs like vomiting, altered sensorium then u need to visit the doctor as these are signs of internal injury to the brain. </s>
