Painful obesity disease mainly manifests as painful nodules or fat masses on top of obesity. Painful obesity is a rare autonomic nervous system disorder of unknown etiology, manifesting as an abnormal accumulation of subcutaneous fat in certain areas of the trunk and accompanied by spontaneous pain in that area. The disease was first described by Dercum (1892) and is therefore also known as Dercum’s disease. What are the examination methods of obesity and painful nodules or fat blocks? 1, autonomic function examination The onset of cardiosomatic diseases, generally speaking, is related to the instability of the autonomic nerves, and most cardiosomatic diseases occur in the organs innervated by the autonomic nerves. Therefore . Autonomic function examination is helpful for the diagnosis of psychosomatic diseases. Commonly used examination methods include oculocentric reflex, prone test, vertical hair reflex, histamine test, postural change test, etc. 2.Cerebrospinal fluid routine test Cerebrospinal fluid is a special body fluid that wraps around and circulates around the brain tissue and spinal cord of the nervous system, which plays a vital role in the protection, nutrition and metabolism of the brain. 3.CT examination of the skull CT examination of the skull is a method of examining the skull through CT. It can clearly show the anatomical relationship between different cross-sections of the skull and the specific brain tissue structure. Thus, it greatly improves the detection rate of lesions and the accuracy of diagnosis. In general, CT has better visualization of human hard tissues than soft tissues. CT examination of the head is important for the diagnosis of most diseases in the skull, cranium and scalp (including trauma, tumor, inflammation, vascular lesions, poisoning, degenerative and metabolic diseases, etc.). 4.CT examination of extremities CT examination of extremities is an imaging technique for bone, joint, muscle and soft tissue lesions of extremities.
