Numbness on one side of the ear may be caused by physiological factors, trauma, auricular cartilage inflammation and other reasons.
1. Physiological factors: If the patient sleeps in a side-lying position for a long time, one side of the ear is compressed for a long time, which causes abnormal local blood circulation, and the symptom of numbness on one side of the ear may occur.
2. Trauma: If one side of the ear of the patient suffers from collision or spikes and other reasons, resulting in damage to the ear tissues, if the endings of the sensory nerves innervating the ear are abnormally affected, the symptoms of numbness on one side of the ear will occur.
3. Auricular cartilage inflammation: when the auricular cartilage membrane is infected by viruses, bacteria, mycoplasma and other factors, resulting in local inflammation, when the secretion of inflammatory factors stimulate the local nerve tissues, involving the surrounding tissues, the symptoms of numbness of one side of the ear may occur.
The cause of numbness on one side of the ear has other causes, such as cervical spondylosis, high blood sugar, etc., should go to the hospital in time for examination and diagnosis, and early targeted treatment.
