I recommend that you schedule an appointment with your primary care physician
can be a difficult thing to diagnose. In general, we think of appendicitis when patients present with right lower quadrant abdominal pain, fever, and decreased appetite. The symptoms usually come on suddenly, and are usually different than those that occurred due to irritable bowel syndrome. For one, symptoms due to irritable bowel syndrome almost never include fever. In addition, most patients with irritable bowel syndrome have a very minimal abdominal tenderness whereas people with appendicitis tend to have significant right lower quadrant tenderness. Diarrhea is also not a symptom of appendicitis typically. Appendicitis is diagnosed usually with a clinical exam and then a CT scan of the abdomen and pelvis with contrast. If the CT scan shows appendicitis, then the patient is usually taken to the operating room for an appendectomy. If nothing is found on the CT, but the clinical suspicion of appendicitis is high, some surgeons
will take their patients to the operating room anyway. Another complicating feature of your case is that you have a urinary tract infection. A urinary tract infection certainly could cause right lower quadrant pain. While the pain typically occurs first in the pelvis, it can travel up to the right or left side into the flank if the infection travels towards the kidneys. Your case sounds complicated. For that reason I would suggest that you schedule an appointment with your primary care physician soon. You need to have this situation evaluated.
