subdural hematoma
A subdural hematoma can develop within hours to weeks after a head trauma, but it commonly occurs within the first 24 to 48 hours after the injury. It is important to monitor for symptoms of a subdural hematoma like headaches, confusion, and neurological deficits in the days following a head injury.
A bump is not bad. It is just an area of swelling. If it was a hard blow or you passed out at all.
Head hematoma should be initially treated with cold therapy (ice pack or cold compress) to help reduce swelling and inflammation. Applying heat can increase blood flow to the area, which may worsen the hematoma. If there is any uncertainty about how to treat it, it's best to seek medical advice.
