_{True numbness is not just a dead/heavy feeling (which is common, and caused even by minor muscular dysfunction in the area), but a significant or complete lack of sensitivity to touch. You have true numbness when you have patches of skin where you cannot feel light touch. Such areas might still be sensitive to pressure: you could feel a poke, but as if it was through a layer of rubber. Most people have experienced true numbness at the dentist. BACK TO TEXT}
Low back pain can be caused by tumors, either benign or malignant, that originate in the bone of the spine or pelvis and spinal cord (primary tumors) and those which originate elsewhere and spread to these areas (metastatic tumors). Symptoms range from localized pain to radiating severe pain and loss of nerve and muscle function (even incontinence of urine and stool) depending on whether or not the tumors affect the nervous tissue. Tumors of these areas are detected using imaging tests, such as plain X-rays, nuclear bone scanning, and CAT and MRI scanning.

Exercise appears to be useful for preventing low back pain.[47] Exercise is also probably effective in preventing recurrences in those with pain that has lasted more than six weeks.[1][48] Medium-firm mattresses are more beneficial for chronic pain than firm mattresses.[49] There is little to no evidence that back belts are any more helpful in preventing low back pain than education about proper lifting techniques.[47][50] Shoe insoles do not help prevent low back pain.[47][51]

^{Spinal laminectomy (also known as spinal decompression) is performed when spinal stenosis causes a narrowing of the spinal canal that causes pain, numbness, or weakness. During the procedure, the lamina or bony walls of the vertebrae, along with any bone spurs, are removed. The aim of the procedure is to open up the spinal column to remove pressure on the nerves.
Arthritis: The spondyloarthropathies are inflammatory types of arthritis that can affect the lower back and sacroiliac joints. Examples of spondyloarthropathies include reactive arthritis (Reiter's disease), ankylosing spondylitis, psoriatic arthritis, and the arthritis of inflammatory bowel disease. Each of these diseases can lead to low back pain and stiffness, which is typically worse in the morning. These conditions usually begin in the second and third decades of life. They are treated with medications directed toward decreasing the inflammation. Newer biologic medications have been greatly successful in both quieting the disease and stopping its progression.}
Strength training is another key part of the “do” category, Dr. Vasileff says. “It’s a good idea to focus on quad, hamstring, and glute strength,” he says. These muscles surround your hips and provide support, along with your core—which is another area to focus on. “Strengthening your core helps to normalize your walking pattern and stabilize how your pelvis and hips move,” Dr. Vasileff says. That translates to less pain and better hip mobility.
Exercise therapy is effective in decreasing pain and improving function for those with chronic low back pain.[50] It also appears to reduce recurrence rates for as long as six months after the completion of program[61] and improves long-term function.[57] There is no evidence that one particular type of exercise therapy is more effective than another.[62] The Alexander technique appears useful for chronic back pain,[63] and there is tentative evidence to support the use of yoga.[64] Transcutaneous electrical nerve stimulation (TENS) has not been found to be effective in chronic low back pain.[65] Evidence for the use of shoe insoles as a treatment is inconclusive.[51] Peripheral nerve stimulation, a minimally-invasive procedure, may be useful in cases of chronic low back pain that do not respond to other measures, although the evidence supporting it is not conclusive, and it is not effective for pain that radiates into the leg.[66]
You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
_{Foraminotomy is an operation that “cleans out” or enlarges the bony hole (foramen) where a nerve root exits the spinal canal. Bulging discs or joints thickened with age can cause narrowing of the space through which the spinal nerve exits and can press on the nerve, resulting in pain, numbness, and weakness in an arm or leg. Small pieces of bone over the nerve are removed through a small slit, allowing the surgeon to cut away the blockage and relieve pressure on the nerve.}

Athletes are at greater risk of sustaining a lumber spine injury due to physical activity. Whether the sport is skiing, basketball, football, gymnastics, soccer, running, golf, or tennis-the spine undergoes a lot of stress, absorption of pressure, twisting, turning, and even bodily impact. This strenuous activity puts stress on the back that can cause injury to even the finest and most fit athletes.

Sciatica is a form of radiculopathy caused by compression of the sciatic nerve, the large nerve that travels through the buttocks and extends down the back of the leg. This compression causes shock-like or burning low back pain combined with pain through the buttocks and down one leg, occasionally reaching the foot. In the most extreme cases, when the nerve is pinched between the disc and the adjacent bone, the symptoms may involve not only pain, but numbness and muscle weakness in the leg because of interrupted nerve signaling. The condition may also be caused by a tumor or cyst that presses on the sciatic nerve or its roots.

Multiple sclerosis (MS) symptoms vary from person to person, and can last for days to months without periods of remission. Symptoms of MS include sexual problems and problems with the bowel, bladder, eyes, muscles, speech, swallowing, brain, and nervous system. The early symptoms and signs of multiple sclerosis usually start between age 20 and 40. MS in children, teens, and those over age 40 is rare. Treatment options for multiple sclerosis vary depending on the type and severity of symptoms. Medications may be prescribed to manage MS symptoms.

A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back, and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.​
If you’re worried you’re headed toward a surgeon’s office, there might be hope. According to the Arthritis Foundation, the best way to avoid hip replacement surgery is to get active in an exercise program. In a study, people who participated in an exercise program for 12 weeks were 44 percent less likely to need joint-replacement surgery six years later than those who did not exercise.
In the vast majority of patients with low back pain, symptoms can be attributed to nonspecific mechanical factors. However, in a much smaller percentage of patients, the cause of back pain may be something more serious, such as cancer, cauda equina syndrome, spinal infection, spinal compression fractures, spinal stress fractures, ankylosing spondylitis, or aneurysm.

The big idea of classification-based cognitive functional therapy (CB-CFT or just CFT) is that most back pain has nothing to do with scary spinal problems and so the cycle of pain and disability can be broken by easing patient fears and anxieties. For this study, CFT was tried with 62 patients and compared to 59 who were treated with manual therapy and exercise. The CFT group did better: a 13-point boost on a 100-point disability scale, and 3 points on a 10-point pain scale. As the authors put it for BodyInMind.org, “Disabling back pain can change for the better with a different narrative and coping strategies.” These results aren’t proof that the confidence cure works, but they are promising.
