During the physical exam, your doctor will gently press on the affected area to determine the location of pain, tenderness or swelling. He or she will also evaluate the flexibility, alignment, range of motion and reflexes of your foot and ankle.
Your doctor may order one or more of the following tests to assess your condition:

- X-rays. While X-rays can't visualize soft tissues such as tendons, they may help rule out other conditions that can cause similar symptoms.
- Ultrasound. This device uses sound waves to visualize soft tissues like tendons. Ultrasound can also produce real-time images of the Achilles tendon in motion, and color-Doppler ultrasound can evaluate blood flow around the tendon.
- Magnetic resonance imaging (MRI). Using radio waves and a very strong magnet, MRI machines can produce very detailed images of the Achilles tendon.
