What Causes Sciatica to Flare Up and How to Relieve It Naturally
Sciatica usually flares up when something adds pressure or irritation to an already sensitive sciatic nerve. The most common triggers are sitting for long hours, bending or lifting with a rounded back, sleeping in an awkward position, sudden bursts of activity after days of rest, stress and tight hip muscles. Most flare-ups settle within a few days to a few weeks with gentle movement, heat or ice, simple stretches and better sitting habits.
