Welcome to Healthcare Magic
You need to rule out spine problems as the pain is radiating towards the back. It can be nerve
compression at the spinal level or even at the base of your foot. You may also have to look for a Calcaneal spur
which can cause pain behind and the sides of your ankle. Get an X-ray of the involved food and also the spine as suggested by your Orthopaedician. You may take pain killers for now under medical supervision to relieve the pain.
