Hello, My Name Is Sherry. I Am 48 Year's Old,female.

Hello, my name is Sherry. I am 48 year's old,female. For the past week my lower back and down both of the back of my legs (muscles) are tingling and hurting so much that i can not sleep at all. I have only slept for about 1 hour each night. I had Scoliosis as a child, and I have a Harrington Rod fused to my spine at the age of 14. I am wondering if i might have a pinched nerve?
