Hello, Welcome to Just Answer and thanks for your question. The trachea is part of the respiratory system. It goes to the lungs and never connects to the stomach. the esophagus, which is located just behind the trachea is the tube that goes from the throat through the diaphragm to the stomach. Pain in that area is generally caused by reflux of stomach acid into the esophagus. Antacids, and acid-reducers like ranitidine, Prilosec, etc. can help relieve this pain. It is unlikely that the change in your cholesterol drug would cause this.
