Abdominal pain with anal cramps and bowel movements may be caused by acute enteritis, prostatitis, urinary tract infection or perianal abscess. 1. Acute enteritis: If you suffer from acute enteritis, the intestinal tract may be infected by bacteria, resulting in acute damage to the intestinal mucosa, more obvious stimulation of the intestinal tract, so there may be a sense of urgency and heaviness. The main clinical manifestations are abdominal pain, anal swelling, and the urge to go to the toilet. 2. Prostatitis: If you have prostatitis, it may lead to prostate congestion and hyperplasia. Because the prostate gland is located in the rear neighbor of the rectum. If the prostate gland is enlarged with inflammation, it may irritate the rectum, resulting in abdominal pain, anal swelling, and urge to pass stool. 3. Urinary tract infection: If there is a bladder or urethra infection, the anus may feel swollen. Inflammation of the urinary system can cause irritation of the bladder and fallopian tubes, which can lead to bladder irritation syndrome. Clinical manifestations are abdominal pain, anal swelling, and urge to poop. 4. Perianal abscess: If there is perianal abscess, it may manifest as anal swelling and continuous throbbing pain. When the anorectal skin is invaded by bacteria and acute inflammation occurs, it may manifest as small abdominal pain. There is an obstruction of blood flow in the veins around the anus, and bacterial infection will form an abscess pus cavity, which may appear as a bowel movement, anal cramping, but more difficult to defecate. If you have abdominal pain, anal distension and urge to defecate, it is recommended that you closely observe your own situation, and if there are any abnormalities, consult a doctor in a timely manner to clarify your condition and follow the doctor’s instructions to give treatment.
