Historically, sciatica was believed to be caused by an infectious lesion of the sciatic nerve. However, advances in medical research have shown that mechanical and functional spinal issues are the primary causes.
Modern understanding of sciatica includes:
nerve root compression (radiculopathy)
sciatic nerve irritation
intervertebral disc herniation or protrusion
joint and ligament dysfunction
muscle spasm and fascial involvement
In most cases, pain occurs not due to inflammation alone, but because of:
mechanical pressure on nerve structures
reduced spinal mobility
muscle imbalance
changes in surrounding tissues
This explains the variety of symptoms, from localized lower back pain to radiating pain, numbness, or tingling in the leg.
Important
Sciatica is not a standalone disease but a symptom indicating underlying dysfunction in the spine or nervous system.
Effective treatment must therefore target the root cause — restoring mobility, muscle balance, and reducing pressure on nerve structures.
Symptoms of Sciatica
Sciatica presents as pain radiating along the sciatic nerve — from the lower back through the buttock, thigh, and down the leg to the calf or foot. It is most commonly caused by compression or irritation of nerve structures in the lumbar spine.
Pain may appear suddenly after lifting, bending, or twisting, or develop gradually, especially in older adults.
Pain Characteristics
Pain may be:
sharp or shooting
burning or pulling
constant or intermittent
It typically:
worsens when bending forward
increases during coughing or sneezing
may decrease at rest
Main Symptoms
one-sided lower back pain
radiating pain into the buttock, thigh, calf, or foot
muscle spasm in the lower back
numbness or tingling in the leg
muscle weakness in the leg
difficulty walking or standing
Additional Signs
pain along the back of the leg
reduced sensitivity
sleep disturbance due to pain
feeling of instability in the leg
increased discomfort with prolonged sitting or standing
In older individuals, pain may be less intense but more persistent and localized in the lower back.
Red Flags (require urgent medical attention)
significant leg or foot weakness (paresis)
difficulty or loss of bladder control
rapid loss of sensation
severe and worsening pain
Important
Sciatica is not a disease itself but a symptom of underlying spinal or nerve dysfunction. Ignoring symptoms may lead to progression and complications.
Diagnosis of Sciatica
Sciatica is a symptom, so the main goal of diagnosis is to identify the underlying cause of nerve irritation or compression. Most commonly, it is associated with spinal overload, muscle imbalance, or intervertebral disc changes (protrusions, herniations).
Risk factors include:
improper lifting with forward bending
weak core and back muscles
prolonged static load
degenerative spinal conditions such as Osteochondrosis
Includes specific tests to assess nerve involvement:
straight leg raise test
muscle tone evaluation
palpation of painful areas
posture and movement analysis
Imaging Methods
If needed, the following are used:
MRI — to assess discs and nerve roots
CT scan — for bone structure evaluation
X-ray — for general spinal alignment
These help identify the exact source of nerve compression.
Approach at “Spine Ambulatory”
Specialists perform a comprehensive assessment, focusing not only on pain location but also on:
muscle function
segmental mobility
load distribution
This allows creating a personalized treatment program targeting the root cause, not just symptom relief.
Treatment of Sciatica
Treatment of sciatica is focused not only on relieving pain, but on addressing the underlying cause of nerve irritation or compression. In most cases, this involves spinal dysfunction, muscle imbalance, and improper load distribution.
Therefore, effective therapy must be comprehensive and individualized.
Main Goals of Treatment
reduce pain and inflammation
relieve muscle spasm
decrease pressure on nerve structures
restore spinal mobility
normalize muscle balance
prevent recurrence
Key Role of the MOK
At “Ambulatoria Spyny,” the MOK (medical wellness system) plays a central role.
It allows working with the spine in a decompressed position, which helps to:
reduce pressure on intervertebral discs
perform gentle traction without axial load
relieve nerve root compression
restore movement safely
During sessions:
deep stabilizing muscles are activated
circulation and tissue nutrition improve
proper movement patterns are retrained
This creates optimal conditions for recovery.
Comprehensive Approach
For best results, the MOK is combined with:
physical therapy — to restore strength and mobility
kinesiotherapy — to correct movement patterns
therapeutic massage — to reduce tension and spasm
manual therapy — to improve joint mobility
Why It Works
Sciatica is not just a “pinched nerve,” but a dysfunction of the entire system:
muscles
joints
intervertebral discs
nervous structures
Addressing all components leads to better and longer-lasting results.
Important
In most cases, sciatica can be treated without surgery. Early intervention helps prevent complications and speeds recovery.
