Is there any one way of treating sciatica that usually works?

Sciatica treatment. Sciatica is not a disease., it is a symptom. It describes pain radiating from your low back and/or buttock down into your leg and foot. It usually is the result of a herniated disc or muscles pressing on the nerve that innervates your leg. The treatment should be tailored to the underlying cause.
No. There are many ways to treat sciatica, it depends on how on each individual responds to therapy.
Sciatica. Pain in the distribution as you suggested describes the pattern of the nerve that travels in the leg called the sciatic nerve. The sciatic nerve is not the cause of the pain source, it is the result of an irritated nerve typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease requiring further evaluation by a spine specialist.
