Feel wrong

Introduction Paraesthesia means an abnormal feeling that is different from the normal person or opposite in nature to external stimuli. Psychological studies on the brain mechanisms of sensory disturbances have confirmed that damage to the posterior region of the central sulcus of the human cerebral cortex is associated with the development of sensory disturbances. If the pain is mistaken for touch, the sense of temperature is mistaken for cold feeling, non-painful stimulation induces pain, and the feeling of cold produces a hot feeling. Feeling inversion is rare in the clinic and is limited to shallow sensations.

Painful temperature sensation

Clinical manifestations:

1. Errors in stimuli, such as misunderstanding of pain as a sense of touch, temperature perception as a cold feeling, non-painful stimulation and a feeling of pain. Feeling inversion is rare in the clinic and is limited to shallow sensations.

2. Feeling inversion is an abnormal feeling that may be different from normal people or opposite to external stimuli. For example, the stimulation of the cold produces a hot feeling. When the cotton ball is lightly touched, the patient develops numbness or pain. More common in snoring.

Differential diagnosis

The diagnosis of feeling wrong:

1. Errors in stimuli, such as misunderstanding of pain as a sense of touch, temperature perception as a cold feeling, non-painful stimulation and a feeling of pain. Feeling inversion is rare in the clinic and is limited to shallow sensations.

2. Feeling inversion is an abnormal feeling that may be different from normal people or opposite to external stimuli. For example, the stimulation of the cold produces a hot feeling. When the cotton ball is lightly touched, the patient develops numbness or pain. More common in snoring.

Differential diagnosis of feeling inversion:

1. Hyperesthesia: refers to the increased sensitivity to external stimuli and a decrease in sensory threshold.

2, hypoesthesia (hypoesthesia): refers to the susceptibility to external stimuli decreased, the sensory threshold increased.

3, feeling inversion (paraesthesia). It refers to an abnormal feeling that is different from the normal person or the opposite nature to the external stimulus.

4, internal sensation (sensual sensation): refers to the feeling of various uncomfortable or unbearable feeling inside the body, are all strange feelings, and often difficult to express. If you feel the body has the special feeling of pulling, squeezing, tearing, turning, swimming, overflowing, flowing, and crawling. It is characterized by the fact that the patient cannot clearly indicate the location of discomfort in the body.
