Differential Diagnosis for Abdominal Pain
Single Most Likely Diagnosis
- Gastroesophageal Reflux Disease (GERD): This condition is characterized by stomach acid frequently flowing back into the tube connecting the mouth and stomach (esophagus). The burning and achy sensation on the left side of the stomach could be due to the proximity of the stomach to the left lower chest area, where GERD symptoms are often felt.
Other Likely Diagnoses
- Peptic Ulcer Disease: Ulcers in the stomach or the first part of the small intestine can cause burning stomach pain, which might be perceived on the left side due to the stomach's position.
- Irritable Bowel Syndrome (IBS): Although IBS typically causes crampy abdominal pain, some individuals might experience a burning sensation, especially if they have a predominance of diarrhea or mixed symptoms.
- Constipation: Severe constipation can lead to abdominal pain and discomfort, potentially feeling like burning or aching, especially if there is significant straining during bowel movements.
Do Not Miss Diagnoses
- Myocardial Infarction (Heart Attack): Although less common in a 34-year-old, it's crucial not to miss a heart attack, as the pain can sometimes be referred to the abdomen, especially the epigastric region, which might be perceived as the left side of the stomach.
- Pancreatitis: Inflammation of the pancreas can cause severe abdominal pain, often in the upper abdomen and radiating to the back. The pain can be perceived on the left side due to the pancreas's location.
- Splenic Infarction or Rupture: Given the left-sided location of the pain, conditions affecting the spleen, such as an infarction or rupture, must be considered, especially if there's a history of trauma or underlying conditions like sickle cell disease.
Rare Diagnoses
- Gastric Cancer: Although rare in young individuals, gastric cancer can cause a variety of symptoms, including abdominal pain and discomfort.
- Inflammatory Bowel Disease (Crohn's Disease or Ulcerative Colitis): These conditions can cause chronic inflammation and ulceration in the digestive tract, leading to abdominal pain, among other symptoms.
- Splenic Flexure Syndrome: A rare condition where the splenic flexure of the colon becomes kinked or twisted, causing abdominal pain on the left side.
