Why Cerebrospinal fluid under pressure in the spinal canal?

Cerebrospinal fluid (CSF) is a clear, colorless fluid that fills the ventricles of the brain and the subarachnoid space, which surrounds the brain and spinal cord. It bathes the brain and spinal cord in nutrients and removes waste products, and it also provides buoyancy and cushioning.

Normally, CSF is produced in the ventricles of the brain and then flows through the subarachnoid space to the spinal cord. It is then reabsorbed into the bloodstream through channels called arachnoid granulations.

If the flow of CSF is blocked, it can cause increased pressure in the spinal canal. This can lead to a variety of symptoms, including:

* Headache

* Neck pain

* Back pain

* Nausea

* Vomiting

* Blurred vision

* Double vision

* Tinnitus

* Vertigo

* Difficulty swallowing

* Weakness

* Numbness

* Tingling

* Incontinence

Increased pressure in the spinal canal can be caused by a variety of conditions, including:

* Congenital abnormalities: Some people are born with defects in the structure of their spine or brain that can block the flow of CSF.

* Head injuries: A head injury can damage the brain or spinal cord and block the flow of CSF.

* Infections: Infections of the brain or spinal cord, such as meningitis or encephalitis, can cause inflammation and swelling that can block the flow of CSF.

* Tumors: Tumors of the brain or spinal cord can block the flow of CSF.

* Hydrocephalus: Hydrocephalus is a condition in which there is too much CSF in the brain. This can cause increased pressure in the spinal canal.

Increased pressure in the spinal canal is a serious condition that can lead to permanent damage to the brain and spinal cord. If you are experiencing any of the symptoms listed above, it is important to see a doctor immediately.
