Introduction

Dull pain in the lower right abdomen may be caused by factors such as the menstrual cycle, muscle fatigue after exercise, pelvic inflammatory disease, appendicitis, or ureteral stones. Avoid eating greasy, spicy, and irritating foods such as chili peppers, ginger, garlic chives, alcohol, pork fat, and fatty meats, as these may irritate the gastrointestinal tract and worsen the pain. During episodes of pain, rest in a comfortable position, such as a semi-sitting posture.

　　In general, dull pain in the lower right abdomen may be caused by factors such as the menstrual cycle, muscle fatigue after exercise, pelvic inflammatory disease, appendicitis, or ureteral stones. If discomfort occurs, seek medical attention immediately. Specific analyses are as follows:

　　1. Menstrual Cycle

　　During the menstrual cycle, the uterus undergoes periodic contractions to shed its lining, which sometimes causes mild pain leading to dull pain in the lower right abdomen. Applying heat packs or gently massaging the abdomen can help relieve the discomfort.

　　2. Muscle Fatigue After Exercise

　　Microscopic damage to muscle fibers during physical activity can trigger an inflammatory response, resulting in the aforementioned symptoms. Rest, gentle stretching, and cold compresses may help alleviate symptoms.

　　3. Appendicitis

　　Appendicitis is commonly caused by infection or improper diet. When the appendix becomes inflamed, inflammatory substances irritate the peritoneum surrounding the appendix, causing pain that radiates to the lower right abdomen, resulting in dull pain in this area. This may be accompanied by symptoms such as fever and nausea. It is recommended to follow medical advice and use medications such as ceftriaxone sodium injection, metronidazole tablets, and penicillin V potassium tablets for treatment.

　　4. Pelvic Inflammatory Disease (PID)

　　Pelvic inflammatory disease can result from various factors, including low immunity and pathogen infection. Infections of pelvic organs can spread throughout the pelvic cavity, causing inflammation and dull pain in the lower right abdomen, possibly accompanied by symptoms such as pain during intercourse and fever. Treatment should follow medical guidance using medications such as azithromycin dispersible tablets, levofloxacin tablets, and amoxicillin capsules.

　　5. Ureteral Stones

　　Ureteral stones are caused by metabolic abnormalities, urinary tract obstruction, and other factors. As stones move within the ureter, they can irritate the ureteral wall, potentially causing dull pain in the lower right abdomen, along with symptoms such as hematuria (blood in urine) and frequent urination. Under the guidance of a qualified physician, medications such as Yishitong pills, progesterone injection, and racemic hyoscine butylbromide tablets may be used for treatment.

　　Maintaining adequate fluid intake helps support normal metabolic and excretory functions in the body.

What tests should be done for a woman with right lower abdominal pain?

Women with right lower abdominal pain generally need to undergo abdominal ultrasound, complete blood count (CBC), urinalysis, gynecological ultrasound, and abdominal CT scan. Abdominal ultrasound can clearly visualize the morphology and structure of abdominal organs such as the appendix, gallbladder, and intestines, helping to identify conditions such as appendicitis, gallstones, or intestinal obstruction. This non-invasive examination provides rapid initial diagnostic information.
