Dysesthesia, a phenomenon that involves one of the 5 senses, touch, but which bothers those who suffer from it at 360 degrees. Let's find out what it is and what the causes may be.

Dysesthesia: meaning and definition

Literally speaking, the term dysesthesia comes from the Greek and combines two words: "Dis", which means "abnormal" and "aesthesis", which means "sensation". It therefore appears that this noun defines an "anomalous sensation".

A little vague as an explanation, let's try to complete it by saying that this strange sensation relates to the tactile sense and it is somewhat unpleasant. By describing the symptoms, in practice, you can better understand what it means to be suffering from dysesthesia.

Dysesthesia: symptoms

It also causes pain, almost always, dysesthesia, and of the feelings that it seems strange to experience without specific reasons. For example that of moisture, on the skin, without it being there presence of liquids or vapors. The sensation of unexplained itching is also associated with this disorder as are the appearance of electric shocks and pins and needles.

On the skin, with dysesthesia, we perceive some temperature variations which do not correspond with the theoretically perceived temperature, that is to say that we can feel del sudden heat without any scientific reason, on the skin. The scientific reason is, in truth, and it is called dysesthesia.

This involves the fact that at the slightest friction, or to the simple and light contact with rough surfaces, and I do not say sandpaper but also just a fabric that is not silk, can be annoying. A classic example of annoyance is that caused by clothes, when you have dysesthesia, another very frequent one to encounter is that of the sheets. If we cannot bear contact with the fabric that covers the bed, sleeping peacefully is a business!

Lower limb dysesthesia

There dysesthesia can also affect the legs, and can do it in a "heavier" way than in other areas of the body by concentrating the most annoying sensations there. In general this disorder can involve the tissues of any body district, those of the lower limbs are certainly among the most affected but they are not the only ones.

In fact, it often happens that i symptoms of dysesthesia affect the mouth or scalp, and imagine what problems they can cause also from the point of view of nutrition and social life.

There is a real term for burning sensations in the mouth, it is "Burning Mouth Syndrome" (BMS), translated as "burning mouth syndrome" which is actually medically a variant of occlusal dysesthesia. There are studies that show how often when a patient suffers from this syndrome, he also has pain in other parts of the body, especially in the legs. There is therefore an annoying twinning between the BMS and "Restless Leg Syndrome" (RLS), or the "restless legs syndrome".


LErythrodysaesthesia, plantar palm, is more commonly called hand - foot syndrome, it is heard above all in the oncological field and is linked to some treatments with oncological drugs following which the patient detects redness and cracks on the palm of the hands and / or on the sole of the foot .

It's not about dysesthesia, indeed. The best known forms of this disorder are different but similar. There is the cutaneous one, which makes every dress you wear become unbearable. That of the scalp, which affects the skull, especially with excessive itching. The occlusal one, o “Ghost bite", Characterized by the sensation that the action of the bite leads out of the intended place.

Dysesthesia and paraesthesia

Dysesthesia can by assonance be confused with anesthesia, with hyperesthesia and also with paresthesia. Respectively these three different phenomena are related to loss, excess or distortion of sensitivity.

Burning dysesthesia

Among the symptoms of dysesthesia there is also the burning sensation, as mentioned, and when that happens it is actually painful. It is as if there is a subcutaneous acid that inflames the skin from the inside. What is defined as, can be a consequence of a state of acidosis of the synapses and the perineural space. Sometimes it coincides with the presence of some nerve lesions, with the lowering of the pH.

Stress dysesthesia

Depression like high stress states can result in momentary dysaesthetic states. In these cases, patients try to relieve pain by also engaging in aesthetic behaviors. Self anxiety is cornic, so is dysesthesia, and causes tingling especially in the face and scalp.
