Hello, As per my clinical experience, the acute pain upper abdomen and lower chest radiating to back may be related to various clinical conditions like: - Acute gastritis - Acute gastric ulcer - Acute duodenal ulcer - Acute pancreatitis - Gall bladder dyspepsia - Others Immediate relief with antispasmodic as dicyclomine or drotaverine along with proton pump inhibitor must be obtained before hand. Later on once the pain is settled and controlled, I recommend an ultrasound of the abdomen & pelvis for the final diagnosis and cure according to the underlying disease. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel, General Surgeon
