When localized itching of the anus occurs at night, the presence of intestinal parasitic infections should be ruled out first. In case of intestinal parasitic infection, some of the parasites will crawl out of the anus at night and cause severe itching at the anal opening, which can be clearly diagnosed by further routine stool tests. After the diagnosis of intestinal parasite infection is confirmed, you should take oral deworming treatment with intestinal parasite tablets, and do regular review and do not eat too cold food. If you’re not sure what you’re looking for, you’ll be able to get a good idea of what you’re looking for. You need to choose metronidazole suppositories or carbomer gel nano-anal administration for anti-inflammatory treatment in the anal canal, and you need to pay attention to a light diet and try not to eat chili, seafood and other irritating foods during treatment.
