Left lower side pain. Please help?

Left lower abd pain. The two most common causes of left, lower abdominal pain are constipation (pain would likely be "crampy") and diverticulitis (an infection of a little sack on your colon), which might have low grade fever and would have a sharper pain when you pressed on it. Women are susceptible to other causes of pain in this area such as pelvic infection or ovary problems.
