How should I help my 91-year-old father who is suffering from back and hip pain?

ADVICE FROM MD/PT. The plan should be based on this persons cognitive and physical status. Physical therapy can help but must be done cautiously with the goal of pain relef. Pool therapy is great if tolerable. Caution should be used with medication due to potential drug interactions and side effects. Evaluate appropriate height of walker/cane and quality of bed/chairs.
