|Back Pain and Leg Pain
|Much more commonly, when lower back pain is accompanied by radiating pain, the radiating pain only travels into the buttock and thigh, and doesn't travel below the knee.
And, most commonly, the thigh pain is found in the back of the thigh, rather than in the front of the leg.
Most of the time, this radiating pain does NOT come from a herniated disc, and does NOT mean the problem is sciatica (caused by an inflamed sciatic nerve, likely caused by a disc herniation).
This type of pain that travels into the buttock and the back of the thigh is usually caused by mechanical changes in the sacroiliac joint and the spinal joints of the lower back. These mechanical changes relate to tight spinal muscles and inflamed spinal ligaments and tendons, with resulting loss of full mobility.
The good news is such problems are treatable with chiropractic health care. The underlying problems are structural, related to the joints and surrounding soft tissues, and chiropractic treatment is designed to restore balance and function. Symptoms typically begin to improve quickly.
In addition to treatment, your chiropractor will likely recommend stretches and exercises to help solve the problem and maintain physical health.
First of all, a little basic anatomy is useful. Spinal discs are weight-bearing shock absorbers. They contain a gel-like ball-bearing center, which is surrounded by tough fibrous cartilage, arranged in concentric, criss-crossing circles.1
As a person gets older, the discs naturally lose some of their water content, and cracks and fissures naturally develop in the fibrous cartilage. If a weight-bearing stress is unusual and unexpected, the gel-like material in the center of the disc can push through one of the fissures and possibly irritate a spinal nerve.
If enough of this material pushes through, the nerve can become inflamed and cause symptoms such as radiating pain and/or numbness, and possibly weakness, in one leg.
Typically, such pain and/or numbness radiates down the leg, traveling below the knee and possibly into the foot.
Such symptoms, with or without back pain, are highly suggestive of an inflamed spinal nerve. In fact, the person will usually say the leg symptoms are much worse and of greater concern than any back pain that may be present.
If the MRI confirms the disc herniation and suggests an inflamed nerve, the diagnosis is complete. What's next?
In the best scenario, conservative treatment may be sufficient and the nerve inflammation improves with time.2,3 Anti-inflammatory medication may be helpful. Chiropractic conservative therapy may include physical therapeutic modalities and gentle trigger point therapy to relieve associated muscle spasms.
A spinal surgeon should be consulted to provide an additional opinion and input. If pain is severe and there is neurologic loss, surgery may be the best option.
Of course, the best management, as always, is prevention. Pay attention to safe lifting procedures. Exercise regularly and get sufficient rest. Your chiropractor will be able to provide guidance and recommend effective protocols to help you achieve and maintain good health and wellness.
