Hi, Thanks for writing in. If not the heart, chest pains commonly occur with reflux disease. Chest pain, which occurs because stomach acid is splashing into the esophagus, is a classic acid reflux symptom. But the pain can last longer and be more intense than expected. Many people mistake heartburn for a heart attack. You can never ignore chest pain, especially if it gets worse when you exercise or exert yourself. It is good that you have got your ECG and blood tests done, results of which are normal. A medicine which reduces the amount of acid made in your stomach is a common treatment and usually works well. Some people take short courses of medication when symptoms flare up. Some people need long-term daily medication to keep symptoms away. Hope this helps
