In one sentence, describe what the following article is about: Stress fractures are fairly common injuries to the foot and ankle. They're especially common in athletes, because they often result from overuse and repetitive stresses, such as those that long-distance runners endure. Sudden increases in activity can also cause stress fractures. For example, if you're usually fairly sedentary but take a hiking holiday, you might end up with a stress fracture. Osteoporosis and certain other conditions that affect bone strength and density make you more prone to stress fractures. Trying to do too much too soon can cause stress fractures. For example, if you're new to exercise and start trying to run a 10k every week, you could end up with a stress fracture. If you feel pain in your foot or ankle that eases when you rest, you may have a stress fracture. If the pain gets worse during normal everyday activities, it's a good sign you have a stress fracture. The pain will also get worse over time. The pain may feel deep inside your foot, toe, or ankle. Pain isn't just weakness leaving your body. If you experience consistent foot pain, especially if it's even during everyday activities or persists when you rest, see your doctor. Ignoring it could lead to worse injury. If you have a stress fracture, you may notice that the top of your foot is swollen and tender to the touch. Swelling may also occur on the outside of the ankle. Sharp pain when you touch an area of your foot or ankle isn't normal. If you experience pain or tenderness when you touch your foot, see your doctor. Bruises don't always occur with stress fractures, but they can. You may be tempted to "tough it out" with the pain from a stress fracture, but don't. If you do not seek treatment for a stress fracture, it can get worse over time. The bone may even break completely.
Summary: Recognize your risk factors. Watch out for pain. Look for swelling and tenderness. Examine the area for bruising. See a doctor.
