I've been getting really bad cramps in my legs. What could it be?

It's possible that you may have a condition called sciatica, which is caused by irritation of the sciatic nerve. Sciatica can cause pain and numbness radiating from your lower back down to your buttocks and legs. The exact cause of sciatica is not known, but it is thought to be due to a combination of factors such as spinal disc degeneration, arthritis, pregnancy, and trauma.
