Since standard over-the-counter remedies aren't providing relief, your mother should be evaluated by a doctor. Persistent chest burning and right-sided abdominal pain can sometimes point to gallbladder issues, such as gallstones, rather than liver problems or simple gas. A physician may suggest an abdominal ultrasound or an endoscopy to identify the exact cause. For treatment, they might prescribe stronger generic medications, such as proton pump inhibitors (like omeprazole or pantoprazole) to reduce stomach acid, or prokinetics to improve gut motility. Please avoid further self-medication and consult a healthcare professional for a safe, targeted treatment plan.

It is common to experience acid reflux, headaches, and body aches after fasting, often triggered by stomach acid buildup and dehydration. Since mild antacids haven't helped, you may benefit from a proton pump inhibitor like pantoprazole or omeprazole, taken on an empty stomach to effectively suppress acid. For the headaches and body aches, paracetamol is a safe option as it does not irritate the stomach lining. Please avoid pain relievers like ibuprofen, which can worsen acidity. Focus on rehydrating with water or electrolytes and eating small, non-spicy meals. If these symptoms persist, please consult a doctor for a physical evaluation.
