Damaged nerves – Strong as wire ropes

Damaged nerves - Strong as wire ropes

Muscle twitching, numbness, and tingling can be utterly harmless discomfort. Sometimes, signs of nerve damage need treatment: fingers become numb and hands furry, legs tingle eyelid twitches, and pudding tastes like soap. Sometimes, nervous disorders can get on your nerves. This is where the causes of abnormal sensations such as numbness, twitching, tingling or unusual smells and tastes lie.

disorders caused by nerve damage

Everything that a person sees, hears, touches, tastes, feels or smells has to be transmitted by the nerves and processed in the brain. Everything done by the body must be sent from the brain to the muscles via the nerves. So, it is not surprising that nerve damage can cause abnormal sensations and movement disorders.

This is also possible when the nerves are no longer adequately supplied due to circulatory disorders, such as in diabetic polyneuropathy, nerve damage that can occur as a result of diabetes.


Lots of connections

Neuropathies can occur in many contexts. Many are harmless, such as the furry feeling on your hands, but others can be severe illnesses, such as diabetes mellitus or the tick-borne infectious Lyme disease. A nervous twitch in the body happens occasionally, for example, in almost everyone before falling asleep. This can happen without being consciously aware of it.

However, it is noticeable on the eyelid, for example. If someone is concerned about their eye twitching, or if it keeps happening for several weeks, they should see a doctor. In most cases, a conversation with the expert can quickly clarify whether there is more to it – for example, the overactive thyroid gland. Usually, however, the twitching is harmless. The cause can be, for example, a lack of minerals, as occurs with heavy sweating. Rest and drinks containing electrolytes help here.

However, diarrhoea or medication can also contribute to an electrolyte shift in the body, leading to tremors or twitching. Sometimes, even hyperventilation – rapid breathing due to excitement, panic, stress or fear – is enough to trigger physical symptoms.

Severe causes of abnormal sensations

On the other hand, the discomfort is not always harmless. Damage to the nerves outside the spinal cord or the brain, known as polyneuropathy, usually begins insidiously with tingling or sensory disturbances in the feet and hands, which can later affect the entire legs and arms.
