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.
