A white, sticky, foamy nose is mainly considered to be caused by wind-cold colds. When you first have a cold, you will have a clear runny nose, and after 1-2 days you will have a white, foamy nose, most of which will be sticky. In Western medicine, it is mainly caused by viral infection, which needs to be actively treated with antiviral drugs, as well as drugs to disperse wind and cold, and nasal comfort tablets. If the disease develops further and is accompanied by bacterial infection, yellow nasal discharge may occur, which needs to be treated with antipyretic drugs and effective antibacterial drugs. If this symptom occurs frequently, it should be considered to be caused by chronic rhinitis or sinusitis, which may be accompanied by headache.
