Patients with severe colds that prevent them from breathing can use local massage to relieve the symptoms of nasal congestion, and if the symptoms still cannot be relieved, medication can be considered. 1. Local massage: For patients who have a severe cold and can’t breathe, massage both sides of the bridge of the nose with fingers, thumbs or two middle fingers to improve the symptoms of nasal congestion by making the local blood flow. If you have a severe cold and can’t breathe, you should take rest, adjust your work and rest, and avoid staying up all night. 2. Medication: If the symptoms cannot be relieved continuously, consider using decongestants, such as oxymetazoline hydrochloride nasal drops and ephedrine nasal drops. For patients with severe cold and nose unable to breathe, if the symptoms can’t be relieved continuously, please consult a doctor in time and seek his/her help.
