Yes, there are several exercises that can help alleviate sciatica symptoms. One effective exercise is the piriformis stretch, where you lie on your back and cross one foot over the opposite knee, then gently pull the knee towards your chest. Another exercise is the knee-to-chest stretch, where you lie on your back and bring one knee towards your chest, holding it with your hands for 20-30 seconds. Additionally, the cat-camel stretch, where you get on all fours and alternate between arching your back upward and downward, can be helpful. However, it’s important to consult with a healthcare professional before starting any exercise regimen for sciatica.
