Burning, Tingling, Prickling Sensation
People with sciatica often feel the pain from the lower spine to the buttock and down the back of the leg, which means that people may feel discomfort along the nerve pathway.
The sensation in the lower body parts described as burning, tingling, prickling, or pins and needles may signify that you have sciatica. This feeling usually replaces the usual feel after experiencing numbness in these body parts. When you have sciatica, and pressure is applied to any of the affected regions, it may cause a burning sensation ranging from mild to severe.
If severe, it may feel like a sudden jolt of electricity that runs through the nerve spots. This sensation may worsen when the person stays in certain positions for too long or makes abrupt movements like coughing or sneezing. So you should go to see a doctor in proper time. [4]
