Why does my leg hurt in this one particular line? Each spinal nerve (nerve that comes off the spinal cord) follows pretty much a pre-determined path. Some stay individual nerves and some bundle together form a bigger nerve like the sciatic. These pre-determined paths provide sensation to the skin and surrounding tissue and are called dermatomes. By asking you to trace your pain, it can help me determine where you need to be adjusted. Pain in the lower back that radiates across the knee? L3. Pain from the neck to the thumb and first finger? C6.
