That depends on the origin and severity of the issue. In some cases, such as a fall or sports injury, it is easy to identify how and why the pain has occurred. Other times, however, there may not be an obvious cause; for example, pain can come on slowly or even after something seemingly minor like a sneeze.
Sciatica occurs when the sciatic nerve – which runs from your lower back down through your legs – becomes irritated somewhere along its path. Diagnostic tests can help determine where this irritation is coming from so that treatment can begin accordingly.
If caused by an accident such as falling onto one‘s buttocks, often de–compressing of the lower back and sacrum resolves the problem quickly.
However, if postural compensation (ie: weight off–center) is causing stress in the lower back resulting in pain then further investigation into these issues must take place with aim of re–centering body weight correctly again to achieve full recovery. Furthermore, pre–existing health conditions (such as scoliosis) could also affect prognosis for recovery time and success rate so must always be taken into account when treating sciatica too. With proper treatment including exercise regimes tailored to each individual case though usually complete resolution of symptoms will occur over time!
