It could be Radiculopathy or Sciatica.
Radiculopathy
When a nerve root (part of a spinal nerve as it exits the spine) between L1 to S3 in your lower back is compressed, you may experience radiculopathy symptoms in your leg. The most common type of radiculopathy involves the sciatic nerve (formed by the L4-S1 nerve roots) and is called sciatica.
Sciatica
Sciatica is typically felt as shooting pain that starts in the back and radiates through the back of the leg into the foot.
A feeling of sudden leg weakness, causing your legs to give out or buckle can be alarming. Weakness in your leg(s) may occur from problems in the nerves and/or muscles in your lower body and is usually treatable. Rarely, the underlying cause may be a serious medical condition requiring immediate medical attention.
Central canal stenosis may occur due to severe disc herniation, abnormally overgrown bone (bone spurs), or thickening of the spinal ligaments.
Other causes include trauma (bleeds) and tumors which grow into the spine.
Why does driving trigger sciatica?
Lower back or leg pain that becomes worse after a long drive is often blamed entirely on the seat or posture, but prolonged driving creates a specific mechanical environment around the lumbar spine and hips that can trigger sciatica.
While driving, the hips remain flexed and the lumbar spine stays in a relatively fixed position for long periods. Unlike walking, where the trunk and pelvis constantly change position, driving gives the lower spine much less movement variety.
The L4-L5 and L5-S1 segments are common areas where disc, joint, and nerve-root symptoms can occur.
If a lumbar nerve root is already sensitive, prolonged sitting may increase buttock, thigh, calf, or foot symptoms. Some people notice that the leg begins to tingle or ache during the drive, while others feel worse only when they get out of the car and take the first few steps.
That pattern does not mean the car seat has damaged the spine.
The more useful question is whether sustained hip flexion, lumbar position, vibration, and reduced movement are reproducing symptoms from an already sensitive structure.
Where does sciatica start?
Your sciatica might NOT start where it hurts, the burning, shooting, or tingling pain down your leg can be linked to irritation of the sciatic nerve somewhere along its pathway, including the lower back or deep gluteal region.
The location of the pain isn’t always the location of the problem.
According to top spine surgeon Dr. Karsten Ritter-Lang, If you are suffering from chronic back or neck pain caused by damaged spinal discs it is likely that minimally invasive procedures like discectomy, laminectomy or decompression, or waiting will only delay the need for surgery, yet spinal fusion is rarely the only option.
These delays can interfere with and eliminate you as a candidate for Disc Replacement Surgery in the future and leave you with spinal fusion as your only option.
Often patients are not offered surgery due to outdated beliefs that surgery should be avoided as long as possible.
New treatments called disc replacement surgery actually should be considered sooner rather than later.
You may have a spinal disc problem, such as a torn or damaged disc.
Torn spinal discs can progress into degenerative disc disease, bulging or herniated discs, sciatica, or numbness in the legs and feet.

Because a significant portion of Dr. Ritter-Lang’s patient base travels internationally for total disc replacement (TDR), his team maintains dedicated international educational and consultation portals:
Better Disc Replacement: betterdiscreplacement.com
Features: Detailed background on multi-level cervical and lumbar disc replacement techniques, patient case studies, and comprehensive guides comparing motion preservation against fusion.
Professional Background & Credentials
Clinical Focus: Over 30 years specializing in intervertebral disc prosthetics, complex multi-level reconstructions, and anterior/abdominal approaches to the spine.
Surgical Experience: Has completed thousands of motion-preserving spine procedures utilizing advanced implants such as M6-C, M6-L, ProDisc, and Mobi-C.
Early Foundations: Trained under Prof. Kurt Schellnack and Dr. Karin Büttner-Janz at Charité University Hospital in Berlin—the research team credited with developing the original Charité artificial disc.
People go to Germany for back surgery primarily to access advanced motion-preserving procedures, artificial disc replacements, and dynamic stabilization systems that may be newer, less restrictive, or harder to find in North America.
