A practical digital ebook for adults whose frozen shoulder keeps interrupting sleep or makes nighttime movement feel uncertain. Learn how to create a repeatable pre-bed setup, support the painful arm, reduce unwanted arm drift, and make more comfortable decisions when you wake or need to reposition. The ebook walks you through back sleeping, modified side sleeping, trunk-led rolling, nighttime comfort checks, fear-driven shoulder testing, and a morning reset that prepares you for the next night. You will also use a seven-night adjustment log to track your starting position, pillow changes, wakeups, and painful movements, while applying the baseline across the next 14 nights. This is an educational guide for building a calmer, more consistent nighttime routine—not a diagnosis or substitute for individualized medical care.
