Why Do My Joints Ache More in My 40s?
Written with Autumn — The Change’s on-device AI perimenopause coach.
The short answer
Joint aches can occur during perimenopause, but joint pain is common and has many possible causes, including injury, overuse, arthritis and infection. The location, swelling, stiffness and effect on daily life matter more than the age on its own.
What the ache is telling you
You may notice stiffness when you first get up, a knee that complains on stairs, or hands that feel different after a long day. Those details are more useful than the broad label “hormonal.”
How perimenopause may fit
The NHS lists muscle aches and joint pains among possible symptoms. The NHS also says that perimenopause and menopause can cause aching and painful joints, while stressing that there are many other causes and that you should not self-diagnose.
Notice the shape of the pain
- Is it one joint or several?
- Is there swelling, warmth or redness?
- Is stiffness worst after rest, or after activity?
- Does pain affect sleep, walking, work or grip?
- Did it start after an injury or a change in exercise?
What may help while you arrange advice
Keep the joint gently moving within what feels safe, vary repetitive tasks and use rest when you need it. A pharmacist or clinician can advise on pain relief that is appropriate for you. Avoid treating persistent pain as something you simply have to accept.
When to get medical help
NHS guidance recommends medical advice when pain is getting worse, keeps returning, affects normal activities or sleep, or has not improved after two weeks. Seek urgent help for a hot swollen joint with fever or feeling very unwell, or severe pain after an injury.
