I recommend that you make an appointment with your primary care doctor
. You mentioned that you have left lower abdominal pain. You said it only occurred once so it doesn't sound like a chronic condition but it is hard to tell at this point. The organs that could be involved in your symptoms that are of concern are your colon, ovaries if you are a woman, and urinary tract. Conditions that involve the colon in that region are diverticulitis and diverticulosis. Diverticulitis is a infectious process that involves outpouching of parts of the colon. It is usually associated with pain in the left lower quadrant. Diverticulosis also involves an outpouching of the colon; however, it is not infectious. It is usually painless but causes bleeding
that can be seen coming from your rectum. If you are a woman, conditions such as ovarian cyst, ovarian torsion, and pregnancy should be ruled out. A cyst is a fluid filled lesion on the ovary. It can burst which can worsen the pain. Ovarian torsion is when the ovary twists upon itself causing a lack of blood supply to the ovary, which can cause pain. Pregnancy should always be of concern if you are sexually active and have abdominal pain. Lastly, a urinary tract infection
can also cause your symptoms. It can start from the tip of your urethra to your kidneys. It is associated with pain on urination and increased urinary frequency. Again, you should make an appointment with your primary care doctor who can examine you and perform simple tests such as a urinalysis.
