Hi welcome to Health care magic forum. Spinal stenosis
can be congenital or due to some disease, ofcourse it could be due to herniation of the disc due to jerk during accedent. any how it is excluded by C.T.scan so you dont worry about it. Besides the pain in the spine and dizzyness
there will be so many symptoms like numbness
etc so the possibility is wholly excluded.
The possibility could be due to concussion
type of head injury
, and jurky sprain
of the back muscles. It may be cleared by muscle relaxants, and anxiolytics.
I advise you to consult a surgeon for diagnosis and treatment, dont think of the stenosis, and use the medicines prescribed. Try to be engaged in Extracuriculars like reading, hearing music etc to avoid tension of anxiety
Wishing for a quick and complete recovery and thanks for calling.
