Sciatica most often occurs when the sciatic nerve is compressed by a herniated disk or bone spur.
Sciatica is characterized by pain that radiates along the path of the sciatic nerve. The sciatic nerve is the largest nerve in the body, beginning at the lower back, and running through the hips and buttocks down to each leg. In most cases, sciatica affects only one side of the body.
Sciatica is a symptom of an underlying medical condition, such as a lumbar herniated disc, degenerative disc disease, or spinal stenosis. It is not a medical condition in and of itself.
Sciatica most often occurs when the sciatic nerve is compressed by a herniated disk or bone spur. This causes inflammation, pain, and sometimes numbness in the affected side. Some cases of sciatic pain can also be due to an irritation of the sciatic nerve during pregnancy.
Trigger Point Therapy
Trigger point therapy can be very effective for treating the symptoms of sciatica. In most cases the pain is associated with trigger points in the gluteus maximus and piriformis muscles. If your therapist practices trigger point therapy, he or she will likely advise 2 or 3 treatment sessions within a short period of time (7 - 10 days). In this period you should begin to feel positive results.
Your therapist may also prescribe or advise a number of self help stretches and exercises for you to perform at home between treatments. In most cases, your likelihood of a successful outcome will increase if you do your "home work".
Below we've provided details of 5 of the exercises which we often prescribe for clients who we are treating for sciatica.
