Hi Dear , As per your query you have chest pain radiating towards shoulders and your have already had tests to rule out cardiac problem . he symptoms you mention in query are pointing towards a condition known as acidic reflux . The condition occur when acidic content of stomach come upward due to upper esophagus sphincter dysfunction . In this type of condition only medicine is not going to work , it also require lifestyle changes . I would suggest you to avoid eating spicy and heavy food specially at night , take small and frequent meals , avoid caffeinated products , take light walk after every meal and continue taking medicine prescribed by doctor . Consult orthopedic surgeon to rule out causes like muscle spasm or cervical spondolysis for shoulder pain . For noe do stretching exercises of shoulders and physical therapy . Hope your concern has been resolved. Get Well Soon Best Wishes, Dr. Harry Maheshwari
