Back pain (Katishoola in Ayurveda) is one of the most common Vata-related disorders. It can occur due to:Vata aggravation → dryness, degeneration (like spondylosis, disc degeneration, sciatica).Kapha blockage with Ama → stiffness, heaviness, inflammatory pain.Muscular strain or wrong posture → imbalance in mamsa dhatu.Other causes – obesity, injury, weak bones (Asthi dhatu kshaya), sitting for long hours.
