**Warning of numbness of hands and feet
Did you know that numbness in the limbs is not only a normal physiological symptom but can also be a sign of many dangerous diseases? Let's find out the causes, symptoms and ways to prevent numbness of hands and feet in this article!
**What is limb numbness?**
Numbness in the limbs is a condition in which the skin on the legs and hands is numb, feeling like ants or needles are pricking the skin. Numbness in the limbs can occur due to many different causes, from simple physiological causes to those caused by serious diseases.
**Causes of numbness in limbs**
According to the National Institute of Neurological Disorders and Stroke (NINDS), more than 75% of cases of numbness in hands and feet are caused by the following dangerous conditions:
- Spondylolisthesis: Spondylolisthesis causes joint cartilage, vertebrae to be worn down, rubbing against nerve roots causing pain, numbness in the neck spreading to the hands or pain from the waist down to the legs.
- Herniated disc: Herniated disc is a common cause of numbness in hands and feet. This is a common problem in the cervical and lumbar spine. When the disc overflows from the disc capsule, it will compress the spinal nerve, causing numbness in the arms and legs, limiting body movement.
- Osteoarthritis: The joints of the hands, knees or hips are worn down, damage due to negative factors will limit movement and lead to numbness of arms and feet.
- Rheumatoid arthritis: The condition of the joints of the hands and feet is inflamed and damaged, causing numbness of the limbs. This symptom is more common after lying down, sitting for too long in one position and is accompanied by stiffness.
- Spinal stenosis: This is a congenital disease, the spine is deformed, shrinking, causing the nerve roots running through to be pinched and causing prolonged numbness of the limbs. This long-term situation will cause blockage of blood circulation, difficulty in movement
- Multiple sclerosis: This is an autoimmune disorder and directly affects the central nervous system, causing damage to the Myelin sheath leading to numbness in the limbs, muscle spasms, fatigue.
- Polyneuritis: The disease occurs when the peripheral nervous system is damaged, causing sensory disturbances and limited movement.
- Atherosclerosis: Atherosclerosis causes narrowing of the blood vessels, compressing the nerves running through and leading to numbness in the limbs. Causes of trauma: Accidents, collisions, and falls that damage peripheral nerves also cause numbness in limbs, limiting movement.
In addition, numbness in the limbs can also be caused by physiological causes such as:
- Blood vessels and nerves are compressed, making it difficult for blood to circulate: numbness in the limbs after birth or due to sitting, standing, sleeping in the wrong position, maintaining a posture for too long, heavy labor, sitting at the computer continuously, driving for many hours...
Vitamin B12 deficiency: Vitamin B12 plays an important role in the production of neurotransmitter fibers. Vitamin B12 deficiency will reduce the transmission capacity of these fibers and cause numbness of the limbs.
Diabetes: Diabetes damages peripheral nerves and causes peripheral nerve complications in patients. People with diabetes often feel numbness in the tips of their toes, especially when lying down, and feel better with exercise.
Cardiovascular disease: Numbness in the limbs can be a warning sign of cardiovascular disease. When the heart works poorly, it will lead to poor blood circulation and numbness of the limbs.
**Symptoms of numbness of hands and feet**
Depending on the cause, the symptoms of limb numbness can vary. Some common symptoms are:
- Feeling like ants or needles are pricking the skin in the skin on the legs and arms
- Burning, hot or cold sensation in the skin on the legs and hands
