The hard mass in the left lower abdomen may be a normal physiological structure, a fecal mass, an inflammatory mass in the intestine, or a mass caused by a malignant tumor, and requires medical attention to determine the cause before appropriate symptomatic management.
The main organs of the left lower abdomen are: the sigmoid colon, part of the descending colon, the distended bladder, and the left ureter. A hard mass can occur in any part of the body with lesions or specific physiologic conditions.
The left lower abdomen may be palpable with normal physiologic structures such as the uterus, a full bladder, well-developed interdigitated muscles of the rectus abdominis tendon, the spine or sacral promontory in those who are wasted, and spontaneously spastic bowel.
Fecal masses are also frequently felt in the left lower abdomen in people with persistent constipation. If the hard mass is movable and the mass disappears after defecation, it is considered likely to be a fecal mass, and if a hard mass appears frequently in this location, a colonoscopy is recommended to check for lesions. It is recommended to eat more fruits and vegetables, drink more water, and drink more yogurt in your daily routine.
Common symptoms of colitis are abdominal pain and diarrhea, often with mucus and bloody stools, along with lower abdominal discomfort and an inability to relieve the stool, although it is tempting to do so. This can cause colon spasm, or prolonged inflammation can lead to thickening of the colon to the point where a mass is felt in the lower left abdomen. Diagnosis relies primarily on barium x-ray enemas and colonoscopy.
It is worth noting that malignant tumors can also present with abdominal masses, which can be accompanied by symptoms such as blood in the stool and changes in bowel habits or properties that require colonoscopy to rule out.
