Appendicitis or something else? I've had a tender lower abdomen since last night. While I'm worried that it's appendicitis, but it's tender in the lower left rather than the lower right. Could this be appendicitis, or something else? .

It . It may be an attack of acute diverticulitis which usually presents with pain in the left lower abdomen but on rare occasion the tip appendix may be in the midline or to the left and cause left lower abdominal pain. Under any circumstance either diagnosis needs to be made immediately to avoid serioous problems. Many things factor into the actual cause of the pain especially if you are a female and you need to see a physician asap. .
The . The appendix is a normal outpouching from the large intestine, usually located on the right side. Diverticulosis is common condition, which are abnormal small outpouchings from the lining of the large intestine (more often found on the left side of the colon), caused by excessive straining while defecating, increasing the pressure in the colon which causes these pouches to form. In general, the appendix and diverticulosis do not cause symptoms unless they become infected. This usually occurs from blockage of the opening of the appendix or the diverticulum. While there are variations of the presentation of the symptoms of appendicitis, in general, the first symptom is often an aching pain that begins around your belly button (navel). The pain may be minor at first, but it becomes more sharp and severe. Your appetite will be reduced and you may have nausea, vomiting, and a low fever. As the swelling in the appendix increases, the pain will shift to your right lower abdomen, to a point right above the appendix (called mcburney's point). This most often occurs 12 to 24 hours after the illness starts. Over the next few hours, there may be increased pain when you walk, cough or move. You may prefer to lie still because sudden movement causes pain. As the infection worsens, the risk for your appendix ruptures, spilling the contents of the colon and infected appendix in to abdominal cavity leading to peritonitis, increasing the risk of complications and death. Diverticulitis can present with localized pain (usually to the left side), fever, diarrhea, but on occasion, if ruptures (as may be seen in appendicitis), can cause peritonitis and abscess formation. In mild cases, antibiotics can soothe the infection. However, if you develop more severe symptoms, or if you have repeated bouts of diverticulitis, you may need to have that segment of large intestine removed. In emergent situations, with abscess and advanced signs of infection, emergency surgery may necessitate removal of part of the large and small intestine and the need for a temporary ileostomy or colostomy. Although your presentation is not classical for appendicitis, there are many other causes of abdominal pain, if you are having worsening pain, you should be seen by a physician for additional testing, including blood work, urine testing, ultrasound or ct scan.
In . In general, left sided pain is more attributable to the sigmoid colon, like diverticular disease. This would be far more common in people over 50 years old. If the pain is unremitting, or associated with fever, or other symptoms like nausea, you should seek medical care immediately.
