What if the child falls a big bag on the back of his head?

If it is only skin trauma, ice can be applied under normal circumstances to achieve the effect of swelling and pain relief, or iodine can be used to disinfect and keep the wound clean. Pay attention to the child's mental state. If accompanied by lethargy, nausea and vomiting, be sure to seek medical treatment in time. Do not rule out the possibility of intracranial hemorrhage.
