Nerve block therapies aim to relieve chronic pain by blocking nerve conduction from specific areas of the body. Nerve block approaches range from injections of local anesthetics, botulinum toxin, or steroids into affected soft tissues or joints to more complex nerve root blocks and spinal cord stimulation. When extreme pain is involved, low doses of drugs may be administered by catheter directly into the spinal cord. The success of a nerve block approach depends on the ability of a practitioner to locate and inject precisely the correct nerve. Chronic use of steroid injections may lead to increased functional impairment.
Approximately 9–12% of people (632 million) have LBP at any given point in time, and nearly 25% report having it at some point over any one-month period.[7][8] About 40% of people have LBP at some point in their lives,[7] with estimates as high as 80% among people in the developed world.[22] Difficulty most often begins between 20 and 40 years of age.[1] Men and women are equally affected.[4] Low back pain is more common among people aged between 40 and 80 years, with the overall number of individuals affected expected to increase as the population ages.[7]
People understandably assume that the worst back pain is the scariest. In fact, pain intensity is a poor indicator of back pain ominousness,10 and some of the worst causes are actually the least painful (especially in the early stages). For instance, someone could experience the symptoms of cauda equinae syndrome, and be in real danger of a serious and permanent injury to their spine, but have surprisingly little pain — even none at all in some cases!
The hip flexors play an important role in everyday mobility and exercise. Involved in pulling the knee toward the hip, most movements either directly or indirectly use the hip flexors. That’s why even the slightest injury can cause great discomfort. Learn how you can recover from a hip flexor injury, and what precautions can be taken to avoid them.
