Hit The Head Until Bleeding?

Hello Ni Made, thanks for asking.

Previously, you should add information such as, how old is your sister, what kind of collision process, how strong the impact light. These things affect the impact of the impact on the brain. If the impact is strong enough, especially if your younger sibling is very young, then it is possible that there is an injury to the brain.

Injury to the brain can result in a concussion (swollen) or brain hemorrhage. Both can increase pressure in the head, causing symptoms such as nausea, vomiting, decreased consciousness (children are easily drowsy, like wanting to keep falling asleep, and decreased response), or seizures. If vomiting is projectile (vomiting spraying or spraying loudly), then it is likely that there is an increase in pressure in the head.

But of course it is also possible that vomiting is caused by other conditions, such as digestive tract infections or respiratory tract, which occur close to head injuries. So, please bring your sister to the doctor. The doctor will assess your sister's awareness and do a CT scan or MRI if necessary. The treatment will be adjusted after the doctor knows the diagnosis.

Hopefully you can find a solution soon. Regards.
