Patients with this symptom have a higher probability of hemorrhoids in general, mostly due to thrombosed or inflammatory external hemorrhoids. Conservative treatment can start with a local anal sitz bath with warm water for 5-10 minutes twice a day, and after the sitz bath you can apply a pain relieving cream to the anus. If the pain is severe, it can also be treated with oral pain medication. After 3-5 days, if the symptoms are not relieved or even aggravated, it is recommended to go to the hospital for relevant examination and treatment, and if necessary, surgery can be performed. In addition, the initial stage of perianal abscess may also show such symptoms, so surgery is recommended, and conservative treatment is not ideal. In addition, older patients cannot rule out the possibility of malignant tumors in the anal canal. Therefore, if such symptoms occur, it is recommended to go to the Department of Proctology of a regular hospital for examination to clarify the diagnosis and then decide on the next step of treatment.
