Regular exercise has the strongest evidence for easing joint pain on aromatase inhibitors. Switching tablets, pain relief, physiotherapy and acupuncture help some women. The goal is to ease symptoms enough to continue hormone therapy. This page sets out what helps and a sensible order to try it.

The short answer
What actually helps joint pain on aromatase inhibitors?
The approach with the strongest evidence is regular exercise, especially a combination of aerobic activity such as brisk walking and strength training. Beyond that, switching to a different hormone tablet, simple pain relief, keeping to a healthy weight, physiotherapy and, for some women, acupuncture have all helped. Many popular supplements have little evidence. The aim is to ease symptoms enough that you can keep taking hormone therapy, because stopping early can reduce its protection.
Why a step-by-step approach works
No single treatment helps everyone. Trying the best-supported options first, and adding others if needed, gives most women a good chance of finding relief without giving up their hormone therapy.
What to try first
Start regular exercise, use simple pain relief as advised, and tell your team how much the pain affects your daily life. If this is not enough after a few months, ask about switching to a different hormone tablet.
When to be checked for something else
A single hot, swollen joint, severe night pain, pain in one bone that does not settle, or new weakness should be assessed, because arthritis, injury or, rarely, cancer in the bone need to be ruled out.

Common approaches and how well supported they are
Not sure whether this applies to you?
Ask an oncologistA practical plan
A sensible order to try things
Begin regular exercise
Brisk walking most days plus simple strength exercises twice a week. Build up slowly over several weeks.
Use pain relief wisely
Paracetamol or short courses of anti-inflammatory tablets, if safe for your stomach, kidneys and heart.
See a physiotherapist
For stiff hands, knees or back, a physiotherapist can tailor exercises and advise on joint protection.
Ask about switching tablets
If pain continues after a few months, a different aromatase inhibitor, or another type of hormone tablet, may suit you better.
Consider acupuncture or other help
Some women benefit from acupuncture from a qualified practitioner, or from a pain clinic referral.
Specific problems
Help for particular joint symptoms
Some symptoms respond to targeted measures.
Stiff hands in the morning
Warm water soaks, gentle finger exercises and thicker-handled utensils make mornings easier.
Tingling fingers at night
Often carpal tunnel. Wrist splints worn at night help, and a steroid injection may be considered.
Tell your team if it persists.A finger that locks
Trigger finger can be treated with splinting, an injection or, rarely, a small procedure.
Painful knees and feet
Supportive footwear, weight management and strengthening exercises reduce load on the joints.
Seek a check if
- A joint is hot and swollen
- Pain wakes you every night
- You notice new weakness

Being straight with you
What these treatments can and cannot do
Most approaches reduce joint pain rather than remove it completely. For many women, that reduction is enough to make hormone therapy bearable. For some, pain remains severe despite every effort, and an honest discussion about the balance of benefit and burden is then reasonable.
Exercise takes time
The benefits of exercise build over weeks to months. It can feel worse before it feels better, so starting gently and keeping going matters.
Switching does not help everyone, but often does
Some women feel much better on a different tablet within weeks; others notice little change. It is still worth trying before stopping treatment.
Be wary of expensive remedies
Many oils, capsules and devices are sold for joint pain. Most lack good evidence, and some may interact with treatment. Check with your team before spending money on them.
What this page cannot tell you
It cannot tell you which option will work for you. Ask your team to help you plan and review your progress.
Exercise in practice
Building an exercise routine that helps your joints
The studies that showed benefit used a mix of regular aerobic activity and strength training. You do not need a gym to follow the same principles at home.
Aerobic activity
Aim for brisk walking or similar activity on most days, gradually building towards a total of about two and a half hours a week. Splitting it into shorter sessions is fine.
Strength training
Two sessions a week of exercises such as chair squats, wall push-ups, step-ups and resistance-band pulls strengthen the muscles that support the joints.
Flexibility and balance
Gentle yoga or stretching improves stiffness and balance, which also helps prevent falls when bones are thinner.
Staying motivated
Keeping going when it is hard
Starting an exercise routine is easier than keeping it up for months, especially on days when joints ache.
Exercise with others
Walking with a friend, joining a yoga group or exercising with family members makes it more enjoyable and easier to stick to.
Track small wins
Noting how far you walked, or how stiff your hands felt in the morning, helps you see progress that is easy to miss day to day.
Adjust rather than stop
On bad days, do a shorter or gentler session rather than skipping entirely. Consistency matters more than intensity.
Your care team
Working with your team to find what helps
Joint pain is easier to treat when your team knows exactly how it affects you. A little preparation before each review makes the conversation more useful.
Describe the impact, not just the pain
Explain which tasks have become hard, such as opening jars, climbing stairs, cooking or sleeping. This helps your oncologist judge how urgent the problem is and which option to try next.
Keep a simple record
Note how stiff you feel each morning, how far you walked and which pain relief you used. A few weeks of notes show clearly whether a change is working.
Review regularly
Agree when you will review progress, often after a couple of months of exercise or a switch of tablets, so a plan that is not working can be changed rather than simply endured.
Commonly believed
What people assume about treating this joint pain
Regular movement and exercise usually help more than rest for this type of joint pain.
These have little good evidence for this side effect. Ask your team before taking them.
Many women tolerate a different tablet better. Switching is worth discussing.
Exercise, pain relief, physiotherapy and switching help many women continue.
Questions we are asked
Common questions about treating joint pain
How long before exercise helps?
Many women notice improvement after several weeks to a few months of regular exercise. Starting gently and keeping going is more important than doing a lot at once.
Is yoga helpful?
Yoga can improve stiffness, flexibility and balance. Combine it with walking or strength exercises for the best effect.
Which pain relief is safest?
Paracetamol is often tried first. Anti-inflammatory tablets can help but are not safe for everyone. Ask your doctor.
Does vitamin D help?
Correcting low vitamin D may ease aches and protects bones. Your team may check your level.
How do I find a physiotherapist?
Ask your oncology team for a referral, ideally to a physiotherapist familiar with cancer patients.
Can I get a steroid injection in a painful joint?
Sometimes, for specific problems such as carpal tunnel or trigger finger. Discuss it with your doctor.
What if nothing helps?
Talk honestly with your oncologist about the benefit of continuing for your cancer, and the options that remain.
Who can help me plan?
Your medical oncologist, with a physiotherapist and sometimes a pain specialist, can help you build a plan.
