After running a red light, my lower abdomen has been slightly painful ever since.

The lower abdomen refers to the lower part of the abdominal region. Persistent mild pain in this area may be related to conditions such as endometritis, salpingitis, or chronic appendicitis. Patients can receive treatment through oral medications, surgery, or other methods. Specific analyses are as follows:

1. Endometritis

When endometrial tissue becomes infected with pathogenic bacteria, it often triggers an inflammatory response, leading to symptoms such as lower abdominal pain, menstrual irregularities, and increased vaginal discharge. Patients may take medications such as Penicillin V Potassium Tablets or Metronidazole Tablets under medical guidance.

2. Salpingitis

Salpingitis refers to infectious inflammation of the fallopian tubes and is one of the most common gynecological conditions among reproductive tract infections. Symptoms may include lower abdominal pain, a sensation of heaviness or pressure, and pain in the lower back or sacral region. Patients should follow medical advice and take medications such as Roxithromycin Tablets or Levofloxacin Hydrochloride Capsules.

3. Chronic Appendicitis

Chronic appendicitis involves long-term inflammation of the appendix and clinically presents as recurrent pain in the right lower abdomen. In severe cases, it may cause fever, fatigue, nausea, and vomiting. When necessary, surgical treatment may be recommended under medical supervision, such as laparoscopic appendectomy or open abdominal surgery.

In addition to the above common causes, persistent lower abdominal pain could also be associated with endometriosis, chocolate cysts, cervical polyps, or other conditions. If symptoms persist or fail to improve, patients should visit a hospital for evaluation and targeted treatment based on the underlying cause.
