What are the type of pains can one experience in the chest?

Chest discomfort post-meal or lying down is often from indigestion or heartburn—a burning sensation behind the breastbone that may extend to the jaw. Gallbladder pain, especially after fatty meals, is typically on the right side and may spread to the shoulder blade, often with nausea. Pain below the breastbone or left side of the upper abdomen that eases with eating is likely stomach inflammation or an ulcer. Chest pain worsening with deep breaths or coughing may stem from a lung issue like pleurisy, often caused by a viral infection. Superficial chest wall pain from muscle, bone, or nerve injury can occur. In females, chest pain from the breasts can mimic heart-related pain.
