Sciatica, known as Gridhrasi in Ayurveda, is a condition causing low back and leg pain. It is often caused by a herniated disc and affects the sciatic nerve. Ayurveda treats it through panchakarma techniques like vasti and virechana to clear doshas. Other treatments include agnikarma, siravedha, local therapies on the lower back/leg, herbs and yoga. Conservative treatments like rest, heat/cold, exercises and acupuncture may also provide relief from sciatica symptoms according to Ayurvedic principles.
