A tibial bone stress injury is damage to the shin bone caused by repeated loading, such as running, that outpaces the bone's ability to repair. It ranges from an early stress reaction to a stress fracture. Most heal with a period of reduced load and a carefully graded return to activity.
Also known as tibial stress fracture, tibial stress reaction, shin stress fracture, bone stress injury
Symptoms
- Shin pain that builds during running or impact exercise
- Pain and tenderness in one small, specific spot on the bone
- Pain that lingers after exercise and may later be felt when walking or at rest
- Aching at night in more advanced cases
- Sometimes mild swelling over the sore area
Causes and risk factors
- Sudden increases in training volume or intensity
- Low energy availability: not eating enough to match training (part of RED-S)
- Low bone density, low vitamin D or a past eating disorder
- Missed or irregular periods in women, or low testosterone in men
- A previous bone stress injury
What the evidence says helps
- An international expert consensus (2025) recommends diagnosis using your history, examination and imaging, with MRI the preferred scan.1
- Most shin bone stress injuries are managed without surgery. Front-of-shin (anterior) injuries are higher risk and need closer medical oversight.13
- A common approach is an initial period of reduced weight-bearing, keeping fit with low-impact cross-training, then a return-to-run plan once daily activities are pain-free.2
- Return to running usually starts with walk-run intervals, building distance before speed. Expert guidance suggests addressing training, strength and nutrition factors throughout.4
- More than 90% of athletes return to sport. Injuries on the inner back edge of the shin tend to recover faster than those on the front.3
- Low energy availability can harm bone health. International guidance on Relative Energy Deficiency in Sport (REDs) supports screening and specialist support where this is suspected.15
Things you can try at home
- Stop running or jumping if you have pain in one spot on the shin, and get it assessed
- Keep fit with low-impact options such as swimming or cycling if they are pain-free
- Make sure you are eating enough to fuel your training, including calcium-rich foods
- Follow official NHS advice on vitamin D, especially in autumn and winter
- When cleared, return gradually and stop if pain returns during or the day after running
When to get urgent help
Contact your GP urgently, call NHS 111, or call 999 in an emergency if you have:
- Pain in one spot on the shin bone that hurts at rest, at night or when walking: see your GP promptly
- Inability to put weight on the leg, or a visible deformity after a fall or impact: go to A&E
- Pain in the front of the shin that keeps coming back: see your GP, as this is a higher-risk site
- Missed periods for three months or more, weight loss or worries about eating: see your GP
- Deep groin or hip pain when running: see your GP urgently, as some bone stress injuries in this area need prompt care
How Apollo can help
We assess your symptoms and history and, if a bone stress injury is suspected, refer you to your GP for imaging. We look at training load, running technique and strength, and ask sensitive questions about energy intake and periods where relevant, signposting to your GP or a specialist if needed. Once medically appropriate, we guide cross-training, progressive strengthening and a staged return-to-run plan.
No GP referral needed. Clinics in Sheringham, Coltishall and Norwich.

Frequently asked questions
How long does a tibial stress fracture take to heal?
Many shin bone stress injuries allow a return to sport in around 6 to 12 weeks. Higher-grade injuries and those at the front of the shin can take several months. Your plan should be guided by symptoms and medical advice.
Will a stress fracture show on an X-ray?
Early bone stress injuries often do not show on X-ray. MRI is the preferred scan because it can detect changes earlier and grade severity.
What is RED-S and why does it matter for bone health?
RED-S stands for Relative Energy Deficiency in Sport. It happens when you do not eat enough energy for your training. Over time this can affect hormones and bone strength and raise the risk of bone stress injuries, so it is worth discussing with your GP.
