Medically speaking, symptoms are all signs that may indicate a disease or injury. These signs are perceived subjectively by the patient, or more precisely client (subjective symptom), and viewed objectively by the physician, or more precisely a third person (objective symptom). Subjective symptoms are also called complaints because they subjectively bother the patient. The totality of these symptoms more precisely complaints result in the complaint picture more precisely the symptomatology. Symptoms and complaints also play a role in hypnosis. This is the case, for example, with acute stress reactions, psychological complaints, but also physical illnesses. In the initial conversation of hypnosis, therefore, the symptoms of the client are also asked.
