Introduction
If there is gluteal fasciitis, nodules may form in the buttocks; these nodules can stimulate surrounding nerve endings, potentially causing numbness in the buttocks after sitting for a while. When a herniated lumbar intervertebral disc compresses nearby nerve roots or the cauda equina, patients may experience such symptoms. During the active phase of piriformis syndrome, the sciatic nerve may become compressed in the buttock area, leading to buttock numbness after prolonged sitting.

Sitting for a while and experiencing numbness in the buttocks may be due to gluteal fasciitis, or it could result from conditions such as lumbar disc herniation. Additionally, this phenomenon may also occur in individuals with piriformis syndrome.

1. Gluteal Fasciitis

If a person has gluteal fasciitis, nodules may develop in the buttocks area. These nodules can stimulate surrounding nerve endings, potentially leading to numbness in the buttocks after sitting for a short period.

2. Lumbar Disc Herniation

Lumbar disc herniation is commonly associated with factors such as trauma, pregnancy, or abnormal spinal development. When a lumbar disc protrudes, it may compress nearby nerve roots or the cauda equina, causing symptoms including buttock numbness after sitting.

3. Piriformis Syndrome

During an episode of piriformis syndrome, the sciatic nerve may become compressed in the buttock region, resulting in numbness after sitting. Patients may also experience additional symptoms such as buttock pain and radiating leg pain.

If the above symptoms occur, it is recommended to visit a hospital for appropriate examinations to identify the underlying cause and receive targeted treatment.
