Joint pain stories often arrive disguised as age. Women write about hands that feel swollen in the morning, hips that complain on the stairs, or knees that seem to have developed a new opinion overnight.

Of 97 women at a similar stage, 58% also mentioned sleep. In joint-pain stories from women 45-55, sleep disruption appeared in more than half of reports.

In the logs, the useful detail is timing. Some women noticed stiffness was loudest after broken sleep. Some saw it cluster around cycle changes. Some brought the pattern into an appointment because the symptom felt too vague on its own.

The cohort does not turn stiffness into one explanation. It shows the kind of notes women used when they wanted the conversation to be more concrete: where it hurt, when it hurt, what else changed, and what had been tried.
