Cold pain at the tip of the ear may be related to the stimulation of cold environmental factors, autonomic nervous system dysfunction, blood circulation around the ear and other factors.
1. Stimulation of environmental factors: in a cold environment, due to the low ambient temperature, the ear warming measures are not in place, which can lead to a gradual decline in the temperature of the skin at the tip of the ear and feel the cold and tingling.
2. Autonomic nerve dysfunction: when the patient is affected by emotions, stress and other mental factors, autonomic nerve dysfunction can occur, the surface of the ear tip skin nerve sensory abnormality, the emergence of the cold and painful abnormal sensations.
3. Periauricular blood circulation disorder: due to local vascular embolism or spasm, periauricular circulation disorder occurs, resulting in poor blood supply to the skin and cartilage at the tip of the ear, which in turn causes the symptoms of cold pain at the tip of the ear.
If the symptoms of cold pain in the tip of the ear, and exclude environmental factors, should actively go to the hospital otorhinolaryngology, under the guidance of the doctor for further examination and treatment.
