What is more severe, subdural or epidural hematoma?

Depends. If you are referring to outcomes, subdural hematomas generally have a worse outcome. This may because these tend to be in older patients and are associated with a rotational component. The blood is also pushing directly on the brain. If you are referring to rapidity of deterioration although both can have a rapid decline, classically, the epidural is more rapid because it is an artery bleeding.
Brain Bleed. An epidural hematoma is a brain bleed occurring outside of the brain but within the skull. This accumulation of blood can cause an increase in pressure within the skull leading to brain herniation if untreated.

Can you fall and get yourself a epidural hematoma or subdural hematoma?

Yes. Acceleration/deceleration injuries (like falling or a car accident) are typically associated with subdural hematomas. On impact, the brain shifts within the skull causing bridging veins to rupture leading to a slow accumulation of blood within the meningeal layers. Read more...
Yes. Epidural hematomas (edh) or subdural hematomas(sdh) can definitely occur after a fall. Anytime one strikes their head on the ground a fracture can occur that can lead to tearing of an epidural artery that can lead to edh. Or the movement of the brain with a fall can tear a bridging subdural vein-thus a sdh. The ground level fall is a common mechanism for both the edh and sdh. Read more...
