I am Spartacus said:
Image shows location of pain only when foot action dorsiflexion is made.
Only one foot affected and the pain is a 'burning' stabbing feeling in that one area.
I have changed my shoes recently and may have over tightened them.. but I am dubious as to that being the cause.
Doesnt affect any activity or performance so curiosity in trying to work out what's going on is why I ask if anyone else has had similar?
Im assuming the pain is in your right foot on the inside of the leg, as per the picture.
If its a stabbing burning feeling then it is more likely nerve compression. This sounds like you are experiencing tarsal tunnel syndrome which cause compression of the tibial nerve. The nerve runs down the inside of your leg and behind the "ankle" or medial malleolus. When you dorsiflex the foot you are reducing the tarsal tunnel space. Doing shoes up to tight also decreases this space making the pain worse.
You need to loosen the shoes, it seems you have already done this, to make sure the nerve is as free as possible. If you are still having problems go and see a Podiatrist as there may be more going on in your feet to cause problems.
