There are two most common types of hemorrhoid edema: first, the formation of a localized blood clot within the hemorrhoid. The second is the edema caused by the protrusion of the hemorrhoid nucleus outside the anus, resulting in impaired blood return, both of which can be accompanied by more obvious pain symptoms. The two cases can be used oral medication plus topical hemorrhoid cream, oral medication can be used Diosmin tablets or elimination stop tablets, topical can be used Ma Yinglong hemorrhoid cream, and then with warm water or warm salt water sitz bath, a week or so time symptoms can be controlled. If the symptoms are still not controlled by the above medications and the pain is still severe, you need to go to the hospital and may need surgery.
