To help with sciatica pain try holding your thumb or middle and index fingers against points which are located on the back of the knees, in the centre of the crease.
Apply firm pressure for at least one minute first at the back of your left knee, then at the back of your right knee.
Pressing these points can help to relieve sciatica and lower back pain. It can also help to reduce stiffness in the back and help flexibility, which can then improve your posture and increase your movements.
It can also help with arthritis in the hips, knees and lower back.
