About the Symptom

Possible Causes
Generally, Numbness or abnormal sensation can be related to:
- Subcortical Hemorrhage
Subcortical hemorrhage refers to bleeding in the subcortical region of the brain. Causes include hereditary abnormalities of blood vessels in the brain, hypertension, and trauma. It is a type of stroke and is a life-threatening emergency that requires immediate medical attention.
- Piriformis Syndrome
The sciatic nerve is responsible for muscle control and sensation of the leg. Sometimes, it can be compressed by the piriformis muscle in the buttocks. This can result in symptoms that are often similar to a slipped disc or nerve compression in the spine.
Ossification of the Posterior Longitudinal Ligament (OPLL)
Ossification of the posterior longitudinal ligament (OPLL) is a condition where a flexible structure called the posterior longitudinal ligament becomes thicker and less flexible.
- Spinal Canal Stenosis
- Carpal Tunnel Syndrome
- Syringomyelia
- Trigeminal Neuralgia
- Transverse Myelitis
Ossification of the Ligamentum Flavum (OLF)
- Arteriosclerosis Obliterans
