The itching near the anus should first be ruled out whether it is caused by the dampness of the local anal skin or the presence of fungi, bacteria and other factors. Secondly, if the patient wears some narrow and inferior underwear, it can also stimulate the skin around the anus to itch. In addition, some common diseases in the anus can also be accompanied by itching symptoms, such as hemorrhoids, anal fissure and other diseases. Due to the retention of local secretions, the wrinkles around the anus become deeper, which will lead to itching near the anus. After the itching near the anus occurs, it is recommended that the patient should go to the anorectal department and dermatology department of the regular medical institution as soon as possible to check and confirm the diagnosis. After the diagnosis is clear, the main treatment method is still to use drugs. As long as the drug effect is not ideal, it can also be treated symptomatically by blocking injection and other methods.
