Stress fracture awareness

Overview

A stress fracture is a tiny crack in a bone caused by repeated force or overuse. It often happens in bones of the foot, leg, or hip. Unlike a sudden break, it develops slowly over time.

Yes, stress fractures are relatively common among active people, especially runners, dancers, and those in the military. They account for a significant number of sports injuries.

Stress fractures most often affect athletes, long-distance runners, basketball players, dancers, and military recruits. They can also affect older adults with weakened bones or people who suddenly start a high-impact activity.

Symptoms

Common symptoms

• Pain that starts gradually during or after activity
• Pain that goes away with rest
• Tenderness when pressing on the bone
• Mild swelling or bruising around the painful area

Symptoms in children

• May complain of vague pain in a leg or foot
• Limping or favoring one leg
• Pain that gets worse with running or jumping

Symptoms in older adults

• Pain that might be mistaken for arthritis
• Greater discomfort during weight-bearing activities like walking
• Pain that persists even with lighter activity

Causes

Main causes

• Repetitive force on a bone from activities like running, jumping, or marching
• Suddenly increasing the amount or intensity of exercise
• Using improper equipment, such as worn-out shoes
• Poor bone health due to low bone density or nutritional deficiencies

Risk factors

• Being female, especially with irregular menstrual periods
• Having osteoporosis or low bone density
• Starting a new high-impact sport without proper conditioning
• Training on hard or uneven surfaces
• Previous history of stress fractures
• Poor nutrition, especially low calcium or vitamin D intake

When to see a doctor

See a doctor urgently if:

• If you have sudden, severe pain and cannot put any weight on the leg or foot
• If there is a visible deformity or you heard a snap or pop during activity

Book a routine appointment if:

• If you have pain during activity that goes away with rest but keeps coming back
• If the pain has lasted more than a week despite reducing your activity

Diagnosis

A doctor will ask about your symptoms and activity, then press gently on the painful area to check for tenderness. Imaging tests help confirm the diagnosis.

Tests that may be done

• X-rays – often normal in the first few weeks but can show a fracture later
• MRI – detailed images that can detect a stress fracture early
• Bone scan – occasionally used, but MRI is more common now

What to expect at your appointment

The doctor may also ask about your nutrition, menstrual cycle (if female), and exercise routine. You might be referred to a sports medicine specialist or physical therapist for further care.

Treatment

Treatment focuses on resting the injured bone so it can heal. Most stress fractures heal without surgery if you stop the activity that caused them. Your doctor will create a plan to help you return to activity slowly.

Self-care at home

• Stop or greatly reduce the activity that hurts
• Apply ice to the area for 15-20 minutes several times a day
• Elevate the leg to reduce swelling
• Use over-the-counter pain relievers (follow package directions and ask your pharmacist if unsure)

Medical treatments

For some stress fractures, your doctor may recommend using crutches or a walking boot to take weight off the bone. Physical therapy can help you safely return to activity. In rare cases, a device that uses low-level electrical current or ultrasound may be used to help bone healing. Always follow your doctor’s advice on activity limits.

When is surgery considered?

Surgery is rarely needed. It may be considered for stress fractures in certain areas that do not heal with rest, such as the front of the shin bone (tibia) or the upper part of the thigh bone (femoral neck). A surgeon may insert a metal pin or screw to stabilize the bone.

Living with this condition

While healing, avoid the activity that caused the fracture. You can often do other low-impact exercises like swimming or cycling, as long as they don't cause pain. Follow your doctor’s timeline for returning to your sport or activity.

Lifestyle tips

• Listen to your body and stop if pain returns
• Gradually increase your activity level, not all at once
• Wear proper, well-supportive shoes for your sport
• Consider cross-training with low-impact activities

Diet and exercise

Eat a balanced diet rich in calcium (from dairy, leafy greens, or fortified foods) and vitamin D (from sunlight or supplements if needed). Stay hydrated. Exercise that strengthens supporting muscles can help prevent future injuries.

Mental health and emotional wellbeing

Taking time off from activity can be frustrating, especially if you are used to being active. It's normal to feel down or anxious. Talk to your healthcare provider if you are struggling. They can suggest ways to stay positive and connect you with a counselor if needed.

Prevention

Yes, many stress fractures can be prevented by gradually increasing your activity level, wearing proper shoes, cross-training, and ensuring you get enough calcium and vitamin D. If you start to feel pain during activity, rest before it becomes a fracture.

Vaccines

Not applicable

Screening programmes

Routine screening for stress fractures is not needed. However, if you have had one before, your doctor may discuss strategies to prevent another.

Complications

If left untreated

• The tiny crack can become a complete bone fracture that needs more treatment
• Chronic pain that does not go away
• Difficulty returning to your sport or activity
• Nonunion – where the bone fails to heal properly

Long-term outlook

The outlook for most stress fractures is very good. With proper rest and gradual return to activity, most people heal within 6 to 8 weeks. Some fractures in areas with poor blood supply may take longer. Following your doctor's advice is the best way to heal fully and avoid future problems.
