why does my left leg go numb when i stand

Leg pain can range from a mild nuisance that comes and goes, to debilitating pain that makes it difficult to sleep, walk, or engage in simple everyday activities. Leg pain often starts as a problem in the lumbar spine, or low back. Watch:
Leg pain and numbness can be experienced in many formsвsome patients describe the pain as aching, searing, throbbing, or burning, or like standing in a bucket of ice water. See The pain can also be accompanied by neurological symptoms, such as a pins-and-needles sensation, numbness, or weakness. The weakness may be persistent, or it may come on suddenly or unpredictably, often described as the leg "giving out. " Leg pain may be caused by a problem in the leg, but often the root cause of the problem starts in the lower back, where the originates, and then travels along the path of the nerve (called sciatica). See Or it could start at the L3-L4 level, where a nerve branches off from the lumbar spine and travels through the front of the thigh. The medical term for leg pain that is caused by irritation of a lumbar nerve root is lumbar radiculopathy. Read about Because the lumbar nerves travel through various parts of the leg and foot, a diagnosis of anyone with leg pain, foot pain, and/or leg or ankle or foot weakness or numbness, should include an examination of the lower back. See Not all leg pain derived from low back problems presents the same way. Some typical descriptions of leg pain and accompanying symptoms include: Burning pain. Some leg pain is experienced as a searing pain that at times radiates from the low back or buttocks down the leg, or it may present as intermittent pain that shoots from the lower back down the leg and occasionally into the foot.


Words that patients use to describe this type of burning leg pain include radiating, electric, or shooting pain that literally feels like a jolt. Unlike many forms of low back pain that can often be a dull ache, for many, leg pain can be excruciating and nearly intolerable. This type of burning pain is fairly typical when a nerve root in the lower spine is irritated, and it is often referred to as sciatica. See Leg numbness or tingling. Anyone who has had a leg or foot "fall asleep" and then gradually return to normal can imagine what numbness in a leg would feel like. Not being able to feel pressure, or hot or cold, is unnerving. Unlike the short-lived numbness of an asleep limb, numbness coming from a low back problem can be nearly continuous and can severely affect a personвs quality of life. For example, it can be difficult or almost impossible to walk or drive a car if oneвs leg or foot is numb. Typical symptoms can range from a slight tingling sensation to complete numbness down the leg and into the foot. Weakness (foot drop) or heaviness. Here, the predominant complaint is that leg weakness or heaviness interferes significantly with movement. People have described a feeling of having to drag their lower leg and foot or being unable to move their leg as quickly and easily as needed while walking or climbing stairs, for example, because of perceived weakness or slow reaction.


Patients with foot drop are unable to walk on their heels, flex their ankle, or walk with the usual heel-toe pattern. See Constant pain. This type of pain is normally felt in the buttock area, so it is not technically leg pain but it may accompany some form of pain felt in the legs. It may also be pain that occasionally radiates past the buttock into the leg. This type of pain is usually described as "nerve pain," versus an aching or throbbing pain. It is typically present only on one side, and is commonly called sciatica or lumbar radiculopathy. It may often be relieved by stretching, walking, or other gentle movement. While the pain is typically on one side, it can occur on both sides if both sides are affected. See and Positional leg pain. If leg pain dramatically worsens in intensity when sitting, standing, or walking, this can indicate a problem with a specific part of the anatomy in the low back. Finding more comfortable positions is usually possible to alleviate the pain. For example, bending or leaning forward slightly may relieve pain from, while twisting (as in a golf swing) can increase facet joint related groin, hip, and leg ache. For most leg pain symptoms, an accurate diagnosis of the underlying cause of problems is an important first step in getting effective treatment. There are a variety of reasons people could experience numb or tingling feet and legs and fibromyalgia is only one.


Other conditions include multiple sclerosis, tarsal tunnel syndrome, peripheral artery disease, and having too much pressure on the nerves. (MS) is an autoimmune disorder that affects the central nervous system. Itвs caused by damage to the myelin sheath. MS is a chronic condition that progresses over time. But many people will have remissions and relapses from symptoms. Numbness and tingling is a common sign of MS. Itвs usually one of the first symptoms that brings people to their doctors for diagnosis. These sensations may be mild, or severe enough to cause trouble standing or walking. In MS, cases of numbness and tingling tend to go into remission without treatment. are a group of nerve disorders caused by nerve damage from diabetes. These neuropathies can affect any part of the body, including the legs and feet. Approximately 60 to 70 percent of people with diabetes experience some form of. Numbness or tingling in the feet is the first symptom for many with nerve damage from diabetes. This is called peripheral neuropathy. The numbness and accompanying symptoms are often worse at night. Over time, and sores may develop on the foot when injuries go unnoticed due to the numbness. These can lead to infections, and coupled with, may lead to amputations. Many of these amputations are preventable if infections are caught early. is a compression of the posterior tibial nerve, which is located along the inner part of the heel. This can produce symptoms that extend all the way from the ankle to the foot, including tingling and numbness anywhere in the foot.


Itвs the footвs version of carpal tunnel. pain, including sudden, shooting pains Symptoms are typically felt on the inside of the ankle and along the bottom of the foot. These sensations may be sporadic or come on suddenly. Seeking early treatment is essential. Tarsal tunnel can cause permanent nerve damage if left untreated for a long period of time. (PAD) is a condition in which plaque builds up in the arteries. Over time, this plaque can harden, narrowing the arteries and limiting the blood supply and oxygen to parts of your body. PAD can affect the legs, which results in numbness in both the legs and feet. It can also increase the risk of infection in those areas. If PAD is severe enough, it could result in and leg amputation. Because PAD increases the risk of heart disease, heart attacks, and strokes, you should consult your doctor immediately if you experience any of the following symptoms: sores on toes, feet, or legs that wonвt heal, slower hair growth on legs or feet If you or have, or, your risk of PAD is higher. Putting too much pressure on your nerves can result in numbness or a pins-and-needles sensation. A variety of different causes can result in having too much pressure on the nerves, including: slipped or herniated discs or back problems that trap a nerve and put pressure on it. In many cases, the underlying cause of having pressure on the nerves is treatable, and in many cases, the nerve damage will not be permanent.
