Most even absolutely healthy people face paresthesia. Numbness of limbs is due to various factors, among which there are serious diseases, and temporary phenomena. To eliminate this condition, it is important to find out why paresthesia occurs.
Nemet left hand - reasons
All the factors provoking the problem under consideration are conditionally classified into 2 groups. The reasons why the left arm is numb:
- Physiological - a violation of blood circulation, squeezing muscles, overstrain of tendons and others.
- Medical - dangerous pathologies of the cardiovascular and nervous system.
The fingers on the left hand
This symptom often arises from harmless factors. After sleep, in an uncomfortable position, prolonged fingers (cutting, typing, knitting), wearing weights and other actions, many people get numb in the left hand within the palm of their hand. Discomfort quickly disappears if you stretch your limb or massage it, restoring normal blood circulation.
Medical reasons why fingers on the left arm grow numb:
- defeat of nerve fibers in the shoulder joint;
- diseases of the cardiovascular system;
- impaired renal function;
- pathology of the lungs;
- liver disease;
- damage to the intervertebral discs of the cervical region;
- neurological ailments.
Nemeth the left hand
If paresthesia extends beyond the fingers, discomfort can be caused by the above-listed physiological causes. At night, the left arm is numb because of an uncomfortable position for sleeping or a prolonged stay in one position. Sometimes discomfort provokes:
- squeezing clothes and accessories;
- professional activity (work at a computer, sewing, etc.);
- injuries, sprains and bruises;
- physical overload.
In other cases, against the background of more serious factors, the left arm (hand) becomes numb - the reasons are:
- arteriosclerosis of blood vessels ;
- acute deficiency of minerals and vitamins in the body;
- damage to the carpal nerve;
- osteochondrosis;
- arthritis ;
- tunnel syndrome.
Nemet left arm from elbow to fingers
The presented variant of a pathology is observed mainly in the mornings, if a person has been sleeping on one side for a long time. Paresthesia can also be caused by other non-dangerous causes listed above. Sometimes the left arm from the elbow dies due to illness:
- angina pectoris ;
- ischemic heart disease;
- pre-infarction ;
- atherosclerosis;
- compression of the nerve;
- inflammation of muscles, tendons, or ligaments;
- arthrosis, elbow joint arthritis;
- osteochondrosis of cervical or thoracic spine;
- avitaminosis.
The left arm is removed from the shoulder
Paresthesia of the entire limb is rare and may indicate serious health problems. When the numbness of the arm from the shoulder to the fingers is fixed after awakening, it is caused by a long stay in one position. This condition is associated with swelling, limb limb. Immediately turn to the doctor you need, if you yourself do not go numb left hand, the reasons often include dangerous pathologies:
- heart disease;
- heart attack;
- Raynaud's disease;
- atherosclerotic plaques in the vessels;
- stroke;
- lung lesions;
- chronic kidney pathology;
- diabetic neuropathy.
The left arm and leg nemet
This combination of symptoms indicates damage to the nerve, its inflammation or pinching. If the left arm grows numb and paresthesia of the lower extremity with edema and pain syndrome is observed in parallel, it is more likely that intervertebral discs are destroyed or hernia progresses. In such situations, mobility is severely limited, the body seems to be constrained. Other serious diseases are also capable of provoking numbness of the hand - reasons:
- tumors;
- phlebeurysm;
- stroke;
- thrombosis;
- multiple sclerosis;
- arthritis and arthrosis;
- mechanical injuries;
- hypothermia;
- diabetes.
What is dangerous numbness of the hand?
The described symptom itself does not pose a threat, but the reasons that cause it can lead to irreversible consequences. The more dangerous the numbness of the hands, depends on the disease that provokes paresthesia. Assume the severity of the problem can be, after observing the course of the pathology. If the numbness quickly disappears, for example, after the restoration of normal blood circulation, its cause was physiological. When paresthesia arises arbitrarily and does not go away without special therapy, it is important to consult a doctor.
The heart hurts and the left arm grows numb
This combination of clinical signs often indicates cardiac lesions. If the left arm grows dumb, the heart can be damaged by the following diseases:
- angina pectoris;
- myocardial infarction;
- pericarditis;
- myocarditis;
- neoplasms in the organ;
- cardiomyopathy;
- atherosclerosis of the heart vessels;
- injury.
There are also less dangerous conditions in which the left arm is numb and there is a pain in the chest area:
- swelling in pregnancy;
- infringement of a nerve;
- deficiency of calcium in the body.
Numbness of the hand with osteochondrosis
This pathology of the musculoskeletal system progresses slowly, but irreversibly. Numbness of the left arm can arise against a background of long-flowing osteochondrosis, when there is inflammation of the intervertebral discs. Their protrusion and destruction, the formation of hernias leads to infringement of the nerve roots. This provokes paresthesia and is accompanied by a marked pain syndrome.
Numbness of hand after fracture
The presented symptom is considered typical for the period of wearing a cast. It immobilizes the limb, constantly supporting it in one position, sometimes squeezing the soft tissues, which provokes numbness of the hand, mainly of the fingers. After removal of gypsum, all signs of paresthesia should disappear on their own. If they do not pass, it is important to establish why the left arm hurts and grow numb. This condition is sometimes a symptom:
- diabetes mellitus;
- Raynaud's disease ;
- abnormal fusion of bone tissue;
- stroke;
- thrombosis of large arteries;
- impaired mobility of joints;
- inflammation of tendons;
- lesions of ligaments;
- carpal tunnel syndrome;
- repeated damage to the extremity by strong overloads.
What should I do if my left arm grows dumb?

- Traumatologist;
- cardiologist;
- endocrinologist;
- urologist;
- vascular surgeon.
In the process of determining the causes of paresthesia will have to perform a number of laboratory tests and undergo clinical studies:
- ultrasound diagnostics;
- radiography;
- magnetic resonance imaging or computed tomography;
- dopplerography;
- electrocardiography;
- urography;
- analysis of urine, blood;
- hepatic assays;
- linked immunosorbent assay;
- hormonal panel;
- a blood test for oncomarkers and others.
Therapy is prescribed only after the establishment, why the left arm is numb - the treatment is completely dependent on the cause of this condition. It may include:
- Reception of medicines. In accordance with the factors that caused paresthesia, anesthetics and anti-inflammatory drugs, antibiotics, vitamins and mineral complexes, hormones, anticoagulants and other drugs are prescribed.
- Physiotherapy. For the normalization of nerve conduction, courses of therapeutic massage, magnetic and radio wave action, compression, water procedures and similar techniques are used.
- Gymnastics. To improve the mobility of joints and muscles, to restore their functions, individually selected sets of exercises are recommended.
