[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. By your history and description these are two possibilities. 1. Worsening of asthma 2. HERD (gastroesophageal reflux disease). So get done PFT (Pulmonary Function Test). If this is normal then no need to worry about worsening of asthma. Possibility of HERD is more in your case because you are having central chest discomfort. HERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms of central chest pain. So avoid stress and tension. Avoid hot and spicy food. Avoid large meals. Start proton pump inhibitors. Go for walk after meals. Keep 2-3 pillows under head in the bed to prevent reflux. Don't worry, you will be alright. Wish you good health. Thanks.
