Oesophagitis and gastritis for many years can keep causing acidity, chest discomfort, and that uneasy feeling after meals. The fact that your pain increases when you press the centre of the chest suggests there may also be muscle or chest wall sensitivity along with acid irritation. Fast heartbeat, nervousness, or a faint feeling after eating can sometimes occur because acid reflux can trigger a stress response in the body. However, since this has been going on for a long time, it needs a fresh, detailed review. When symptoms do not improve despite treatment, it is important to reassess rather than continue the same medicines. Your doctor may review your reports again, suggest further tests such as pH monitoring or motility studies, and adjust treatment only if needed after proper evaluation. Sometimes a different approach is required rather than just increasing medicines. Daily habits can make a big difference. Eat small, frequent meals, avoid spicy and oily food, and do not lie down for at least 2-3 hours after eating. Elevate your head while sleeping, reduce stress, and avoid caffeine or smoking. If chest pain becomes severe, spreads, or is associated with breathlessness, seek urgent medical care.
