It hurt from my waist to my foot, terrible muscle spasms from my butt and down the length of my left leg. After seeing the doctor I was put on a medication called Gabapentin; it took better than a week for it to work. The spasms slowly stopped with the medication working from my waist down first the spasms stopped in my butt then a few days later they stopped in my thigh, then slowly to my knee, my shin, my calf and finally about a week later I was free of muscle spasms. Have been on Gabapentin for 2 years now. Free of sciatic nerve pain, what a relief. I had no idea that those parts of my body could hurt so much.
