There is a clear distinction between visceral discomfort and visceral hallucinations: visceral discomfort is a sensory abnormality and visceral hallucinations are a perceptual abnormality. The location of visceral discomfort is not clear, and there may be indescribable discomfort and pain inside the body, but visceral hallucinations are mainly abnormal sensations fixed to a certain organ, such as a feeling of twisting and breaking of the heart, stomach, or intestines. It is difficult to describe the exact location, nature, and pain symptoms of visceral discomfort, and most of the manifestations are some pulling sensations, wandering sensations, insect bite sensations, and other problems, while visceral hallucinations are clear in location and painful discomfort is more clearly described, such as a very clear feeling of pain, fracture, perforation, burning sensation, etc. Visceral discomfort is mainly seen in neurological disorders such as hypochondria and anxiety disorders, and visceral hallucinations are mostly seen in psychological problems such as schizophrenia and menopausal psychosis.
