[|Human|] my son was hit by a car about three week ago, he fractured his pelvis in three places but no other injurys. A couple days ago he started complaining about being dizzy, lightheaded, and passing out standing up. I called the hospital and they said there is nothing relating to the accident that would cause this.
[|AI|]  HelloThanks for query. Treatment of fracture of the pelvis depends upon the displacements of bones. If there is stable fracture and no displacements of bones detected on X-ray no treatment is required except rest for 6 weeks. The symptoms of dizzies, light-headed on standing is most likely to be due to postural hypotension that develops after one suddenly stands from lying down position, and it is due to pull of major chunk of blood in legs resulting into momentary reduced blood flow to brain. You may get him checked by a qualified Physician to rule out any other cause for these symptoms. Getting up gradually from lying down position and sitting for a while before standing helps to resolve the issue. Chat Doctor.
