True sciatica refers to pain below the knee originating from sciatic nerve irritation.
Often people feel pain in the lower leg which can be referred from many structures in the spine including disc, ligament and joint tissue.
Muscles in the back rarely refer pain below the knee. Irritated spinal ligaments and joints can cause reflexive increases in muscle tone which feels like a muscular cause. The deeper issues always lie in the deep spinal structures.
We use a system of assessment and treatment at The Physio Joint which analyses the effect of movement in changing pain. By using carefully applied repeated and sustained guided movements of the spine, we can find the best ways to move your spine to reduce irritation on spinal tissue.
