If the nose is pinched red, it is caused by trauma resulting in skin capillary dilation, congestion and edema. If it is within 24 hours, it is recommended to apply a local cold compress to prevent the nose from becoming congested and edematous, thus reducing excessive glandular secretion and increasing vascular congestion and edema. If it is 24 hours after the trauma, it is recommended to apply local hot compresses to improve microcirculation, facilitate the expansion of skin pores, facilitate metabolism, facilitate drainage and improve the symptoms of congestion and edema, and never squeeze and dig the nose in the near future to prevent the symptoms of congestion and edema from worsening. Generally, after the above methods of treatment, the symptoms will gradually return to normal, no need to worry about fear. If the skin of the nose has bruising symptoms, the recovery time will be longer.
