Sciatica is a severe painful condition where sciatic nerve of one or both the legs are involved. Thanks to long hours sitting jobs, it is a common disease which affects the movement of the legs. Often it is associated with low back pain. The condition where back pain and radiating pain of the legs are found together it is called Sciatica syndrome. In older times, as per Ayurveda system of medicine, it was named as Gridhrasi.
As per Ayurveda, gridhrasi (sciatica) is explained as one among 80 types of Vata imbalance disorders(neurological / neuro-muscular disorder). The word ‘Gridhrasi’ is derived from the root word – ‘Gridhra’. which means the bird ‘vulture’.
It is observed that in this disease, the patient’s gait is altered as his legs become tense, and slightly curved due to pain. Ultimately, the patients walk similar to the walk of the vulture (gridhra). Hence the name Gridhrasi.
According to another saying, sciatica is characterised by severe pain experienced by the patient and it is similar to the pain one experienced by the prey of vulture, while being eaten up.
