This sciatica exercise is one of my favourites. It doesn’t work for everyone though so you need to discuss it with your physiotherapist before trying it out and seeing how you get on.
Try lying on your front and gently stretching backwards. Start off just lifting your trunk onto your arms. If that feels comfortable try stretching up a bit further like the model in the illustration below.

This exercise should not worsen your pain. It should especially not worsen any leg pain you may have. If you find its a little bit tough on the lower back then ease off and reduce the amount of stretch.
If you find that your sciatica symptoms are worsening then stop this exercise immediately and discuss it with your doctor or physical therapist.
Not all of these exercises will be suitable for everyone with sciatic back pain - you need to get the right ones for you.
If your physiotherapist agrees try a few minutes of these exercises on and off throughout the day.
