For temporary relief of mild headaches and joint pain, paracetamol (acetaminophen) is generally a safe over-the-counter option, provided she has no liver issues. Avoid giving NSAIDs like ibuprofen without consulting a doctor, as they can cause stomach or kidney complications, especially in older adults. Because headaches and joint pain can be linked to various underlying conditions ranging from high blood pressure to arthritis, it is highly recommended that she visit a physician for a proper diagnosis and a safe, personalised treatment plan.
