An embedded hemorrhoid is actually an acute local circulatory disorder that can cause tissue ischemia and hypoxia and even bring about an acute inflammatory response. With the prolongation of the impaction, the anal sphincter will spasm, and the spasm will further make the lymphatic return of the hemorrhoid veins poor will cause swelling, causing severe pain. If it lasts for a longer period of time, ulceration of varying degrees will occur and a blood clot will form. At this point the pain will be very intense and painful if it does not pass. If it continues to progress, harmful toxins will be absorbed into the blood and will cause systemic symptoms, even systemic sepsis, fever, and other conditions. If this happens, it is important to seek prompt medical attention. The early stages of rectal impaction only require manual retraction and the nucleus of the embedded hemorrhoid can be retracted. If necrosis occurs at a later stage, surgery may be required, and the complications and healing time after surgery will be longer, so it is important to seek medical attention in a timely manner when this situation occurs.
