VAS, visual analog scale.
Most patients (9/12) reported discomfort when they ate cold food, including exacerbated dysphagia and regurgitation (7/12) or aggravated chest pain attacks (2/12). Two patients never ate cold food and only one had no discomfort after eating cold food. All patients reported no additional discomfort when they ate hot food. In addition, 8 out of 12 patients tried drinking hot water to relieve their chest pain attacks, effective in 5 patients and not in 3 patients.
