Quick Answer
Urgent care evaluates abdominal pain and can diagnose many common causes with on-site lab testing and X-ray. CityHealth San Leandro provides same-day evaluation and treatment. Walk-ins welcome.
Abdominal pain is one of the most common reasons people visit urgent care. The cause can range from mild (gas, indigestion) to serious (appendicitis, kidney stones).

Diagnosing Abdominal Pain at Urgent Care
At CityHealth, our providers use a systematic approach to evaluate abdominal pain. This includes:
- History and physical exam: Location, onset, duration, quality (sharp, cramping, burning), and what makes it better or worse
- Urinalysis: Checks for UTI, kidney stones, and other urinary causes
- Blood work: Complete blood count (infection markers), metabolic panel (liver, kidney function), lipase (pancreas)
- Pregnancy test: For women of childbearing age — an important cause of lower abdominal pain
- Referral for imaging: If appendicitis, gallstones, or an obstruction is suspected, we can order an ultrasound or CT scan at a nearby imaging center

Abdominal Pain by Location — What It Might Mean
Where your pain is located often provides important diagnostic clues:
- Upper right: Gallbladder (gallstones, cholecystitis), liver, right lower lobe pneumonia
- Upper left: Spleen, stomach (gastritis, ulcer), pancreatitis
- Upper center (epigastric): Stomach, GERD, peptic ulcer, pancreatitis, heart (referred pain)
- Lower right: Appendix (appendicitis), right ovary (ovarian cyst, torsion), hernia
- Lower left: Diverticulitis, left ovary, constipation, IBS
- Lower center: Bladder (UTI), uterus (menstrual pain, fibroid), pelvic inflammatory disease (PID)
- Generalized/entire abdomen: Gastroenteritis, constipation, gas, IBS, early appendicitis, bowel obstruction
Home Care for Mild Abdominal Pain
For mild abdominal discomfort that doesn’t require immediate medical attention:
- Stay hydrated: Sip clear fluids, especially if nausea is present
- Heat therapy: A warm (not hot) heating pad on the abdomen can help with muscle cramps or menstrual pain
- Avoid irritants: Stay away from alcohol, spicy or fatty foods, caffeine, and NSAIDs if the pain is gastric in origin
- OTC antacids: For heartburn or GERD-related pain (Tums, Pepcid, Zantac)
- Rest: Allow the digestive system to recover
If mild pain worsens significantly over 24–48 hours, or if any of the emergency signs above develop, seek care immediately.
