Pustules on the side of the nose may be considered as rosacea. The disease is mostly caused by excessive stress, anxiety or genetic factors, which leads to local capillary dilation and inflammatory reaction around the hair follicles, resulting in the production of pustules. In addition to pustules, clinical manifestations can also appear in the form of papules, folliculitis papules, papules and other rashes, accompanied by a certain itching sensation. In clinical treatment, topical clindamycin metronidazole application and oral metronidazole tablets can be used. If the patient has a normal retinal macula and normal liver and kidney function, he can choose to apply hydroxychloroquine sulfate tablets orally.
