One of the common signs of damage to the nervous system is numbness of the limbs. In rare cases, the disease is associated with vessels and systemic diseases. What makes the left leg go numb and how to cope with the problem?
Possible causes of numbness
Numbness of the lower limbs occurs when the following diseases:
- lumboischialgia – numb of the foot and pain in the area of the sciatic nerve;
- disk hernia;
- polyneuropathy – manifested in alcoholism and diabetes. In most cases, not only the left leg becomes numb, but also the hand;
- Raynaud’s disease – the activity of small vessels is disrupted, resulting in a spastic reaction;
- varicose veins and thrombosis;
- stroke – especially common in patients over the age of 40;
- multiple sclerosis;
- Morton’s neuroma;
- tunnel syndrome;
- frostbite or injury.
In 90% of cases, the left leg becomes numb due to the development of an intervertebral hernia. In order to avoid complications, it is necessary to start treatment promptly. Therapy is carried out comprehensively and includes the following methods:
- spinal correction using manipulation techniques;
- treatment with muscle relaxants or corticosteroids;
- physiotherapy, which includes ultrasound treatment and laser therapy;
- specially designed charging or kinesitherapy (new method). When dosed loads, vertebral muscles are strengthened.
Why Numb left leg and arm
Numbness of the trunk and extremities on the left side may occur as a result of circulatory disorders in the right hemisphere of the brain, that is, during a stroke. According to statistics, it is the hemorrhage in the brain – the most frequently diagnosed cause of the phenomenon.
As a rule, the lack of sensitivity is accompanied by a violation of movements, speech and vision impairment.
Attentiveness should be shown to those who have a predisposition to the development of diseases associated with the brain.
Stroke provoking factors:
- atherosclerosis of the brain;
- excess weight;
- heartbeat rhythm disturbed;
- taking hormonal contraceptives;
- smoking abuse;
- thrombosis (increased).
Other less common causes of numbness of the limbs of the left half of the body include the following diseases:
- brain cancer;
- traumatic brain injury;
- diseases associated with the violation of the myelin sheath of nerves. A vivid example is multiple sclerosis.
Numbness of the thumb on the left foot – the reasons
The lumbar spine is responsible for the functioning of our limbs. If the numbness does not affect the whole leg, but only a part – the finger, foot, and
- inflammation of the sciatic nerve;
- violation of metabolic processes;
- spinal tuberculosis;
- developing gout;
Based on the above factors, it is impossible to find the only treatment. When the thumb on the left leg becomes numb, only a specialist can prescribe a specific treatment. A symptom can develop almost any disease. For example, a patient with diabetes will have to inject and take medication all his life. There is another situation with osteochondrosis: the treatment process will be long. In this case, you will have to turn to manual therapy, drugs, massage, and even traditional medicine.
But most often the numbness of the big toe occurs as a result of bad habits. Alcohol and tobacco, entering the body, unnaturally expand (constrict) the vessels. Regular exposure ultimately leads to impaired functioning of the limbs.
Numbness of the left leg from the hip to the knee
Flowing occurs in three typical areas:
- The groin area on the left side is numbed and gives to the upper thigh. As a result, Roth syndrome appears. That is, when you exit the pelvis, nerve fibers are squeezed;
- Numbness of the zone from the left thigh to the buttock (back). Clear signs of the manifestation of the syndrome of the pear muscle;
- Numbness occurs over the knee almost in the inner part of the leg. In this case, the person feels shooting pain.
All of these symptoms are associated with a degenerative-dystrophic process in the muscles. There is a violation of the innervation of the muscles and infringement in the narrow channels of the nerve fibers.
Numbness of the heel of the left leg: causes and consequences
In 80% of cases in people from adolescence to adulthood, the heel becomes numb due to the presence of an intervertebral hernia. To confirm the diagnosis, it is necessary to do a magnetic resonance imaging of the spine. Refusal of medical care will lead to an increase in weakness and lameness. Also left leg goes numb from the knee to the foot. As a result, a person will not be able to walk, stand on their toes, and urgently need neurosurgical intervention.
To establish the causes, it is necessary to pass blood tests, make an x-ray, MRI of the waist, brain, neuromyography, undergo a neurological examination and go to an ultrasound of the vessels.
- heel pain syndrome occurs during constant loads on the foot;
- bone fracture (talus);
- paresis of the foot;
- lesion of the central nervous system as a result of multiple sclerosis or stroke.
- correction of the spine using manual techniques. The goal is to restore the work of the PDS;
- optimize the motor stereotype;
- to eliminate the overload of the intervertebral discs, to restore muscle tone, to comply with the orthopedic mode;
- reduce inflammation and tissue edema.
Compliance with these measures is sufficient to avoid complications and repeated exacerbations.
Before visiting a specialist, minimize the load on the heel area: change your shoes to a spacious one and be careful not to receive injuries.
Why left leg is numb below the knee
Numbness can occur when a person is sleeping, sitting, or walking. As a rule, the phenomenon is accompanied by accompanying symptoms:
- cramps begin in the legs;
- itching lower part (below the knee);
- skin from the knee to the foot is also subjected to numbness;
- aching pain occurs;
- goose bumps;
- leaking legs (especially while tilting forward);
- pain in the buttocks and lumbar area;
- freezing feet.
With the above symptoms, the specialists make the following diagnoses:
- osteocondritis of the spine;
- hernia intervertebral;
- disc protrusion.
It should be understood that it is impossible to treat a separate part of the leg at the initial stage of the disease. Significant symptoms occur during the advanced stage of the disease. Treatment can begin only after the differential diagnosis. It is important to reduce the amount of physical activity and strictly monitor the orthopedic regime.
Many cases have been recorded in which patients managed to completely get rid of the disease, but an untimely visit to the doctor complicated the situation. The longer a person suffers pain and numbness of the limbs, the higher the likelihood of neurosurgical intervention.
