Sciatica
Sciatica is a specific type of back pain that is pretty easy to diagnose, although it is reported as being highly uncomfortable. People with sciatica experience pain along the sciatic nerve, which is the largest nerve in your body.
The sciatic nerve begins at your lower back and then splits at the base of your spine to extend further down to your buttocks, legs, and finally ends at the bottom of each foot.
The sciatic nerve can become compressed or irritated, which causes a “shooting,” “stinging,” or “burning” sensation in your lower back, buttocks, legs, or feet.
