Hello and welcome, I understand that you have a burning pain on the left side. The common cause of this pain is the growing uterus pushing the stomach up and leading to acid reflux. Other cause may be iron induced gastritis, chest pain related to heart problems. If the pain is due to acidity, you must stop the paracetamol as it will increase the acidity. Also stop the iron for a few days till the pain is controlled. You are already on anatacids. Just take frequent small meals low in spices and fat. Avoid fruits and meals that are sour or bitter. Drink cold milk in small quantities. Do not lie down immediately after meals. Get an ECG done to rule out any heart problem if the pain is persistant. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have. Dr Madhuri Bagde Consultant Obstetrician and Gynecologist
