Causes and treatment of numbness in the legs: doctor’s advice
About the symptom
Numbness in the legs is a common symptom that can occur in people of various age groups. It is characterized by sensations of tingling, burning, or complete loss of sensitivity in the legs. This condition can be temporary, for example, as a result of remaining in one position for a long time, but it can also be a sign of more serious diseases. Numbness often arises from the compression of nerves or blood vessels, which may be associated with injuries, disc herniations, or other pathological conditions.
It is important to note that numbness can be accompanied by other symptoms, such as pain, weakness, coordination issues, and movement problems. These signs may indicate the presence of serious diseases, such as diabetic neuropathy, multiple sclerosis, or stroke. If numbness in the legs is persistent or progressive, it is necessary to consult a doctor for a thorough examination and determination of the cause of this symptom. Proper diagnosis and timely treatment can significantly improve quality of life and prevent potential complications.
Diseases
Numbness in the legs can be a symptom of various diseases related to both the nervous and vascular systems. Often, numbness occurs as a result of nerve or blood vessel compression, which can lead to insufficient blood supply and disruption of nerve impulse transmission. Among the diseases associated with numbness are diabetic neuropathy, osteochondrosis, multiple sclerosis, and carpal tunnel syndrome.
There are also more serious conditions that can manifest as numbness. For example, thrombosis or significant narrowing of the arteries leads to impaired circulation, which in turn causes sensations of numbness and weakness. Therefore, it is important not to ignore this symptom, especially if it is accompanied by other manifestations such as pain, burning, or changes in sensitivity.
- Diabetic neuropathy
- Osteochondrosis of the spine
- Multiple sclerosis
- Carpal tunnel syndrome
- Deep vein thrombosis

Types of Leg Numbness
Leg numbness is a common symptom that can manifest in various forms and intensities. It is important to understand that this condition can be temporary and occur as a result of an improper body position, but in some cases, it may signal serious illnesses. Depending on the cause and localization, numbness can affect only one leg or both, and it can vary in duration—from brief to constant.
There are several types of leg numbness, classified by localization and symptoms. For example, it can be complete or partial numbness, where sensitivity is lost in certain areas, such as the foot, calf, or thigh. Patients often note that numbness is accompanied by tingling, burning, or a “pins and needles” sensation. Additionally, numbness can arise due to nerve compression, such as during prolonged sitting, or more serious conditions caused by neurological or vascular diseases.
- Numbness of the toes
- Numbness of the foot
- Numbness of the calf
- Numbness of the thigh
- Numbness of both legs
Causes of Numbness in Legs
Numbness in the legs can be caused by a multitude of factors, each requiring careful analysis. One of the most common causes is nerve compression, which can occur due to prolonged positioning, such as sitting with crossed legs. In this case, usually, simply changing your position a little is enough to feel improvement. However, persistent or recurring numbness may indicate more serious health issues.
Another common cause of numbness in the legs is conditions related to circulation. Atherosclerosis, diabetic neuropathy, and varicose veins can significantly affect blood flow to the extremities, often leading to tingling sensations and loss of feeling. Neuropathies of various origins, including alcoholism and certain infections, also frequently contribute to this symptom.
- Nerve compression
- Circulation problems (atherosclerosis, varicose veins)
- Diabetic neuropathy
- Neuropathies (alcoholism, infections)
- Injuries and spinal cord damage
- Vitamin deficiencies (especially B vitamins)
- Multiple sclerosis
- Herniated intervertebral discs
Common Related Pathologies
Numbness in the legs can be a symptom of various diseases that may affect both the nervous and vascular systems. Such pathologies include nerve compression that occurs in the presence of intervertebral disc hernias, as well as sometimes in cases of radiculitis. These conditions can lead not only to numbness but also to pain, making timely consultation with a doctor extremely important.
It is also worth noting that numbness in the legs may be associated with peripheral artery diseases, such as atherosclerosis. Narrowing of the vessels restricts blood flow to the extremities, which can cause feelings of tingling or numbness. Additionally, diabetic neuropathy, which develops with prolonged diabetes, can also lead to similar symptoms due to nerve fiber damage.
- Intervertebral hernia
- Radiculitis
- Atherosclerosis
- Diabetes mellitus
- Diabetic neuropathy
- Carpal tunnel syndrome
- Peripheral arterial disease
- Multiple sclerosis
- Nerve injuries
