Lie on your back on a comfortable surface.
Bring the affected leg toward the abdomen.
Hold it below your thigh, and slowly stretch your knee as far as you can without forcing it.
Bend again and repeat the movement.
Do 10 repetitions , and do 3 sets with rest between each one.
Exercise 3: Seated piriformis stretch

The piriformis muscle can squeeze against the sciatic nerve if it’s tight. This stretch aims to reduce that pressure.

How to do it:

Sit on a firm chair or comfortable surface.
Cross your affected leg over your healthy leg (as if forming a “4”).
Hold the tip of your foot and slowly lower your knee toward the floor.
Hold this position for 15 seconds , without forcing or bouncing.
I repeated the movement 3 to 4 times.
Additional tips

Perform these exercises in comfortable clothing and in a quiet place.
keep a steady, relaxed breathing throughout the movements.
Do not do the exercises if you suffer from stabbing pain, severe tingling, or weakness.
Consistency is key: practice these stretches at least three times a week to see improvements.
In summary
Sciatica can be very restricting, but with proper, gentle, and progressive movements, you can relieve much of the discomfort. These three exercises are an excellent way to begin, always with caution and drawing attention to your body’s signals.
