Right Lower Abdominal Pain: Causes and Next Steps

Right lower abdominal pain?

Hello Doctor: For the past two days, I have been experiencing pain in my lower right abdomen (the pain worsens with turning, stretching, movement, or when pressure is applied).
I visited a gastroenterology clinic where the doctor performed an ultrasound and indicated that the pain is not located in the area of the appendix, but did not rule out the possibility of appendicitis.
The doctor initially suspects it may be intestinal inflammation and administered an injection as well as prescribed oral medication, but I have not seen any improvement.
My bowel movements are normal (about twice a day, with no diarrhea).
What could be the possible causes, and what further tests should I consider?

Dr. Huang Zhihui reply Surgery

When a young person experiences right lower abdominal pain for the first time, acute appendicitis is indeed the primary consideration.
For most general surgeons, the diagnosis is usually not too difficult and relies mainly on symptoms, medical history, physical examination, and blood tests.
If necessary, imaging studies may be used to assist in the diagnosis.
However, in some cases, the symptoms may not be typical, making it challenging for physicians to arrive at a definitive diagnosis.
Therefore, physicians may opt for ultrasound or computed tomography (CT) scans to aid in diagnosis, or they may choose to observe the patient or attempt antibiotic treatment.
However, if during the observation period the symptoms or clinical course begin to suggest appendicitis, surgical intervention should be performed promptly.
In addition to appendicitis, other possible conditions include diverticulitis, mesenteric lymphadenitis, urinary stones, cholecystitis, peptic ulcers, constipation, tumors, and parasitic infections, among others.
It is advisable to return for a follow-up if symptoms do not improve.

More Info

Right lower abdominal pain can be a perplexing symptom, as it can arise from various underlying conditions. Given your description of the pain, which intensifies with movement, pressure, or certain positions, and the fact that you have already consulted a gastroenterologist who performed an ultrasound, it is essential to consider several potential causes and next steps.

Possible Causes of Right Lower Abdominal Pain
1. Appendicitis: While the ultrasound did not indicate appendicitis, it is still a possibility that cannot be entirely ruled out, especially if the pain persists or worsens. Appendicitis typically presents with sharp pain that may start around the belly button and then localizes to the right lower quadrant.

2. Diverticulitis: Inflammation of diverticula in the colon can cause localized pain, often accompanied by changes in bowel habits. Although you mentioned normal bowel movements, diverticulitis can still be a consideration.

3. Irritable Bowel Syndrome (IBS): This functional gastrointestinal disorder can cause abdominal pain, bloating, and changes in bowel habits. Stress and diet often exacerbate symptoms.

4. Ovarian Issues: In females, conditions such as ovarian cysts or ectopic pregnancy can cause right-sided abdominal pain. Given your gender, this is an important consideration, especially if there are any menstrual irregularities or other gynecological symptoms.

5. Musculoskeletal Pain: Strain or injury to the abdominal muscles or ligaments can cause localized pain, particularly if it worsens with movement or pressure.

6. Hernia: A hernia in the inguinal region or other areas can cause pain, especially when straining or lifting.

7. Infection or Inflammation: Conditions such as pelvic inflammatory disease (PID) or urinary tract infections (UTIs) can also manifest as abdominal pain.

Next Steps for Evaluation
Since you have already undergone an ultrasound and received initial treatment without improvement, consider the following steps:
1. Follow-Up with Your Doctor: It is crucial to communicate the lack of improvement to your healthcare provider. They may recommend further imaging studies, such as a CT scan, which can provide a more detailed view of the abdominal organs and help identify any issues that an ultrasound might miss.

2. Blood Tests: A complete blood count (CBC) can help identify signs of infection or inflammation. Additionally, liver and kidney function tests may be warranted to rule out other systemic issues.

3. Gynecological Evaluation: If you have not already done so, a visit to a gynecologist may be beneficial to rule out any ovarian or uterine conditions that could be causing your pain.

4. Dietary Review: Keeping a food diary to track any correlations between your diet and symptoms may help identify potential triggers, especially if IBS is suspected.

5. Pain Management: Discuss with your doctor about adjusting your pain management regimen. Sometimes, medications such as antispasmodics or specific dietary changes can provide relief.

6. Physical Examination: A thorough physical examination by your healthcare provider can help assess for any signs of hernia or musculoskeletal issues that may not have been previously evaluated.

Conclusion
Right lower abdominal pain can stem from a variety of causes, and it is essential to pursue further evaluation if initial treatments do not yield results. Keeping an open line of communication with your healthcare provider and advocating for further testing is crucial in identifying the underlying issue. Remember, timely diagnosis and treatment can significantly impact your recovery and overall health.
