fracture healing flare ups

Overview

A fracture is a broken bone. After a fracture, your body works hard to repair the break. Sometimes, during that long healing process, you may get a 'flare-up' — a time when pain, swelling, or stiffness becomes worse than it has been. This can be concerning, but it is often a normal part of healing. However, it can also be a sign that something needs attention.

Yes. Most people with a healing fracture will have at least one flare-up of symptoms as their bone repairs itself and as they start using the limb more.

Fracture flare-ups can happen to anyone with a broken bone. They are slightly more common in older adults, people with weaker bones (osteoporosis), and people who return to activity too quickly.

Symptoms

Common symptoms

• Increased pain around the break
• Swelling or a feeling of warmth
• Stiffness or reduced movement
• A dull ache that comes and goes
• Tenderness when you touch the area

Symptoms in children

• Limping or not wanting to walk on the affected leg
• Crying or being irritable when moving the limb
• Guarding the injured area
• Going back to pain after being pain-free for a while

Symptoms in older adults

• More pain at night or when resting
• Morning stiffness in and around the fracture
• A slight increase in swelling after activity
• Feeling unsteady or fearful of using the limb

Causes

Main causes

• Normal healing activity inside the bone can cause pressure and inflammation
• Starting to use the limb more than the bone is ready for
• Muscle and joint stiffness from being immobile
• Changes in the weather or air pressure
• The bone not healing at the expected rate (delayed union)

Risk factors

• Smoking
• Poor nutrition or low vitamin D
• Osteoporosis or a previous fragility fracture
• Diabetes or other conditions that affect circulation
• Obesity, which adds stress to healing bones
• Certain medicines that affect bone healing (check with your doctor)

When to see a doctor

See a doctor urgently if:

• If your pain or swelling is getting worse over several days
• If you have a fever or feel generally unwell
• If the fracture site feels unstable or you hear a grinding sound

Book a routine appointment if:

• If flare-ups happen frequently or last longer than a few days
• If you are not sure whether your fracture is healing well
• If you have questions about resuming activity

Diagnosis

A healthcare provider will listen to your history and examine the bone. They will check how the fracture feels and look for any signs of infection or poor healing. They may order imaging to see the bone.

Tests that may be done

• X-ray (most common to check bone alignment and healing)
• MRI scan for soft tissues and stress reactions
• CT scan for more detailed images
• Blood tests if an infection is suspected

What to expect at your appointment

The exam is usually quick. You may be asked to move the limb or allow the provider to gently press around the fracture. You may have an X-ray to see if the bone has moved or how much new bone has formed.

Treatment

Flare-up treatment depends on the cause. For most normal flare-ups, simple self-care measures will get you through. If there is a sign of infection or poor healing, your provider will recommend the right next step.

Self-care at home

• Rest and prop up the injured limb
• Apply a cold pack wrapped in a cloth for 15 to 20 minutes, several times a day
• Use over-the-counter pain relief only after checking with your pharmacist or doctor
• Try gentle, suggested exercises from your physiotherapist
• Avoid heavy lifting or high-impact activity until your provider clears it

Medical treatments

If the flare-up is due to overuse, your provider may suggest a period of rest or adjust your immobilisation. If the bone hasn't healed well, they may refer you for physiotherapy or talk to you about options like bone healing stimulators or further imaging. They will always explain the risks and benefits before recommending any procedure.

When is surgery considered?

Surgery is only needed if the bone fails to heal, infection develops, or the fracture is badly displaced. In those cases, an orthopaedic surgeon may realign the bone and hold it with pins, plates, or rods. Most flare-ups do not require surgery.

Living with this condition

Try to keep as much normal activity as you can without overloading the healing bone. If you need a cast, splint, or crutches, use them as directed. Talk to your physiotherapist about how to stay safe while doing everyday tasks.

Lifestyle tips

• Do not smoke, it slows bone healing
• Limit alcohol, which can affect bone health
• Get plenty of sleep and manage stress
• Stay active with safe exercises that don't stress the fracture
• Use supportive footwear for balance and comfort

Diet and exercise

Your bones need calcium, vitamin D, and protein to rebuild. Include dairy, green vegetables, eggs, fish, and beans in your meals. For exercise, ask your physiotherapist about safe muscle-strengthening moves you can do without irritating the fracture. Once healed, regular weight-bearing activity helps bones get stronger.

Mental health and emotional wellbeing

Living with a fracture can be frustrating. A flare-up can make you worry that you are slipping backwards. It's natural to feel low, anxious, or annoyed at times. If these feelings don't fade, speak to a doctor or counsellor. You don't need to handle it alone.

Prevention

You cannot prevent every flare-up after a fracture, but you can lower your risk by following your recovery plan, increasing activity gradually, eating well, avoiding smoking, and staying hydrated.

Vaccines

There is no specific vaccine for fracture flare-ups, but keeping your general vaccinations up to date, like tetanus, can prevent infections that might interfere with healing.

Screening programmes

For older adults or people with risk factors, a bone density scan can help identify osteoporosis. Ask your healthcare provider if you should have one, as treating weak bones can prevent future fractures.

Complications

If left untreated

• The fracture may heal in a poor position (malunion)
• The bone may take much longer to heal or fail to heal (non-union)
• An infection in the bone can spread and become serious

Long-term outlook

The vast majority of fractures heal, and flare-ups usually resolve with rest and sensible management. Recovery can take months, but with patience, support, and medical advice, most people get back to their normal activities. If a flare-up is a sign of a problem, early treatment usually leads to a good outcome.
