Various stretches and yoga poses can help to ease the symptoms of piriformis syndrome, a condition that causes discomfort in the buttock, lower back, and often even the entire leg.
Pull the left knee up to the chest and grasp the knee with the right hand. Pull it towards the right shoulder and hold for a while (at least 5 seconds and gradually increase the duration). Repeat this on the other side, with a different leg and different arm.
Lie flat on the back with the feet on the floor and the knees bent. Rest the ankle of the left leg over the knee of the right leg. Repeat this on the other side too.
It is important to mention that no stretch should be held for too long, especially if the pain is severe. Hold each stretch for five seconds, and increase the time to at least 30 seconds a day when you feel ready for it.
