You can expect your skin and nails to be checked for discoloration, hydration, and signs of wounds, infections, or any growths. The doctor will check your pulse on top of your feet and the inside of your ankle to check that the arteries are providing adequate circulation. The legs are observed for swelling and discoloration which, among other things, may represent disease of the veins that bring blood away from the foot back to your heart. The nerves of your legs and feet will be examined by checking reflexes and how well you feel certain types of sensation applied to areas around your feet. The doctor may gently squeeze the joints of your foot to see if they are painful, as well as moving them to see if the motion is restricted or painful in any way.
For additional help arriving at an accurate diagnosis, the podiatrist may order a X-ray exam of your foot, as well as certain types of scans, including MRI, or magnetic resonance imaging. Vascular tests, such as Doppler ultrasound, may be needed. Your podiatrist may also order blood and urine testing. For certain types of skin growths or tumors of the foot, a biopsy may be required. The biopsy can range from a very simple needle aspiration to an open surgical procedure.
