When to Consider an X-ray for Foot, Ankle, or Lower Leg Pain

If you’re experiencing pain or discomfort in your foot, ankle, or lower leg, it’s important to see your doctor promptly. After a physical exam, your doctor may recommend an X-ray to determine if a fracture or another bone-related issue is causing your symptoms.

Why X-rays Are Useful

X-rays are particularly effective for evaluating bone and joint concerns, though they are less effective for diagnosing soft tissue or ligament injuries. Your doctor may order an X-ray to identify:

  • Abnormal bone growths
  • Arthritis
  • Bone tumors or cancer
  • Fractures and broken bones
  • Bunions
  • Bone infections
  • Dislocated joints
  • Normal bone development in children
  • Presence of foreign objects
  • Bone alignment following treatment

How X-rays Work

X-rays use low levels of radiation to produce images of the inside of the body. Dense materials such as bone or metal absorb the radiation and appear white on the image, allowing your doctor to see fractures, growths, and other abnormalities.

While the radiation exposure from a single X-ray is minimal and generally safe for adults, pregnant women should inform their doctor beforehand. In such cases, protective measures like a lead apron may be used to shield the fetus.
