While stomach pain is usually nothing to worry about, you will know if it’s serious if you experience the following symptoms: severe belly pain that lasts several days, bloody stools, pain while urinating, vomiting, heartburn that lasts longer than two weeks, and blood in the urine. Your doctor may have a closer look to determine if your stomach pain stems from a more serious underlying health problem. Your examination will involve a blood test, x-ray, CT scan, ultrasound, or an ECG (Electrical Tracing of the Heart). Your doctor will want to know everything to help treat your pain. There are many reasons for abdominal pain, and your doctor may be concerned about gallstones, ulcers, infections, appendicitis, and pregnancy problems. What’s interesting is that your pain might not be coming from the abdomen. Some causes include heart attack, pneumonia, certain conditions in the groin or pelvis, some skin rashes like shingles, and problems with stomach muscles.
