Muscle twitching, deafness, tingling can be quite harmless sensations. Sometimes, however, they are signs of nerve damage that needs to be treated: the fingers become numb and the hands furry, the legs tingle, the eyelid twitches and the pudding tastes like soap. Sometimes a nerve disorder can really get on your nerves. Because here are the causes of abnormal sensations such as numbness, twitching, tingling or unusual odor and taste impressions.
Disorders due to nerve damage
Everything that man sees, hears, feels, tastes, feels or smells must be passed on by the nerves and processed in the brain. And everything that is done by the body has to be transmitted from the brain through the nerves to the muscles. So it is not surprising that in nerve damage can cause abnormal sensation and movement disorders.
This is also possible if the nerves are no longer properly supplied due to circulatory disorders, such as in diabetic polyneuropathy, a nerve damage that may occur as a result of diabetes.
Neuropathies can occur in many contexts. Many are harmless, such as the furry feeling on the hands, but others can be serious illnesses such as diabetes mellitus or tick-borne infectious disease Lyme disease. A nervous twitching on the body occurs again and again, for example, in almost every person before falling asleep. That can happen without being aware of it.
On the eyelid, for example, it stands out, however. If someone is worried about his eyelid twitching or if the twitching happens again and again for several weeks in a row, he should go to the doctor. Usually a conversation with the expert can quickly clarify whether there is more behind it - for example, the overactive thyroid gland. As a rule, twitching is harmless. Cause can be, for example, a lack of minerals, such as occurs in heavy sweating. Calm and electrolyte drinks help here.
But even diarrhea or medication can contribute to a shift in electrolyte in the body, which leads to shaking or twitching. Sometimes even hyperventilation - fast breathing due to excitement, panic, stress or anxiety - is enough to cause physical symptoms.
Serious causes of discomfort
On the other hand, the sensations are not always harmless. Damage to the nerves outside of the spinal cord or the brain, the so-called polyneuropathy, usually begins creeping with tingling or sensory disturbances in the feet and hands, which may later affect the entire legs and arms.
