Joint pain and morning stiffness on aromatase inhibitors

Aromatase inhibitors, such as letrozole, anastrozole and exemestane, lower oestrogen levels to protect against breast cancer returning. Oestrogen helps keep joints lubricated and reduces inflammation, so when it falls, many women develop aching, stiffness and sometimes swelling in the hands, wrists, knees, hips or feet. It is one of the most common side effects, often starting within the first few months, and it is the leading reason women stop these tablets early. The good news is that it can often be eased.

What it usually feels like

Stiffness worst first thing in the morning or after sitting still, aching in several joints, reduced grip, and sometimes tingling in the fingers from carpal tunnel. It often eases with movement during the day.

What helps most

Regular exercise is the best-studied approach, particularly a mix of walking and strength training. Keeping to a healthy weight, simple pain relief, and switching to a different aromatase inhibitor or to tamoxifen also help many women.

When to look for another cause

Pain in one joint only, a hot red joint, severe swelling, or bone pain that does not ease should be checked, because other conditions, including arthritis or rarely cancer spread to bone, need to be ruled out.

Joint symptoms on aromatase inhibitors are real, common and sometimes very disabling. They are not a sign of weakness or imagination. At the same time, many women find ways to ease them enough to continue treatment, which protects against recurrence.

It often improves over time

For some women, symptoms are worst in the first year and then settle somewhat, especially with regular exercise.

Stopping resolves it, but at a cost

Symptoms usually ease within weeks to months of stopping, but stopping early can reduce protection against recurrence. That is why trying other options first is worthwhile.

Not every remedy is proven

Many supplements and oils are promoted for joint pain, but few have good evidence. Check with your team before taking supplements, as some interact with treatment.

What this page cannot tell you

It cannot tell you which approach will work for you. Ask your team to help you try options in a sensible order.

Hand stiffness is particularly common and can affect cooking, writing and daily chores.

Warm-up routines

Soaking hands in warm water, or gentle finger and wrist exercises in the morning, often loosens stiffness.

Practical aids

Jar openers, thicker-handled utensils and wrist supports at night can reduce strain. An occupational therapist can suggest more.

Tingling fingers

Numbness or tingling, especially at night, may be carpal tunnel. Tell your team, as wrist splints and other treatments help.

Stiff hands and aching knees can make ordinary tasks tiring. A few adjustments reduce strain through the day.

Pace your tasks

Spread heavy chores across the week, take short movement breaks when sitting for long periods, and avoid staying in one position too long.

Adjust your workspace

A chair with good support, a keyboard at the right height and comfortable footwear can ease pain for women who work at desks or on their feet.

Ask for help

Sharing tasks such as grinding, washing clothes by hand or carrying heavy loads with family members on bad days can protect your joints.
