Numbness: Other causes

Numbness: Other causes

Polyneuropathy as the cause of numbness

Polyneuropathy is a peripheral nervous system disease associated with sensory disturbances and numbness in the hands and feet. These are triggered by irritated, inflamed or damaged nerve tracts. Depending on the cause of the disease, there may be other symptoms, for example, muscle weakness.


Diabetic Polyneuropathy

A unique form is diabetic polyneuropathy, which is accompanied by typical diabetes symptoms such as severe thirst, frequent urination, fatigue and exhaustion. In addition to diabetes, polyneuropathy can also be caused by chronic alcohol abuse, poisoning or infections. If polyneuropathy is the cause of the numbness, the treatment depends on the type of polyneuropathy.

The herniated disc is the cause.

In the case of a herniated disc, pressure on the nerve root can cause pain in the area supplied by the nerve. These are often accompanied by tingling or numbness. If such symptoms occur, a doctor should always be consulted as a precaution. He can examine whether there is a herniated disc and whether it should be treated conservatively or by surgery. However, the latter is usually only necessary in severe cases.

In addition to a herniated disc, other problems in the spine, especially in the cervical spine, can also cause numbness in the hands, feet or on the skin. The numb feeling usually occurs with an unpleasant tingling in the affected limbs. Therefore, if you have persistent problems with your sense of touch, consider having yourself examined by an orthopaedist.


stroke as a cause

In the event of a stroke, the brain is no longer supplied with sufficient blood and, therefore, no longer with sufficient oxygen and nutrients. Various disorders occur since the affected area can no longer function. These disorders can also include nervous failures.

Nervous failures can cause arms or legs to feel numb and no longer be able to move. Typically, such numbness occurs on one side only after a stroke. Other symptoms that can indicate a stroke are headaches, dizziness, nausea, visual and speech disorders and signs of paralysis. If you suspect you may have had a stroke, you should call a doctor immediately.

Infections, migraines and tumours as triggers

Various infections with bacteria or viruses can cause a numb feeling in the body. Such infections include, for example, shingles or Lyme disease. Depending on the type and severity of the infection, the doctor treating you will prescribe appropriate medication; bacterial infections are usually treated with antibiotics.

A numb feeling in the head or face is often the harbinger of a migraine attack. In addition, such a numb feeling can also indicate circulatory disorders and tumours in the brain, as well as anxiety or panic attacks. Burns, frostbite, or disturbances in the facial nerves can also cause numbness. Multiple sclerosis (MS) can also lead to a numb feeling in the face, but also in the arms or legs.

Finally, a vitamin B12 deficiency can also trigger numbness, which often occurs on the tongue . There can also be sensory disturbances in the hands and feet. Vitamin B12 is crucial for our nervous system, and a deficiency can lead to disorders in the central nervous system. In addition to feeling numb, symptoms such as paleness, tiredness and concentration problems can also become noticeable with such a deficiency.
