Sensations+Pain - Foot. I should do.

I did some walking for 20 days (6-7 km each day) I did not do any stretches at all and my ankles are rather weak. - Sensations started as shocks on the sole of my foot. - Now for the past month and a half I have sensations on the top on my foot to my toes that come suddenly. It feels like needles dragged on the inside. - When I walk I have pain behind the ankle (above the heel to above the ankle bone) - The inside of my ankle feels like its stretching from within. - I have little toe pain sometimes when I walk. - I have a pinch like sensation below my little toe when I walk that sometimes burns. - I have muscle spasms. - Sometimes there is what feels like a line of slight pain along arch. - These sensations and pain happen when I walk and stand (about 10 minutes) - I did a NCV Test-no compression.Still not sure what is aggravating the situation. - Thyroid normal - No Diabetes - Did physiotherapy to relax muscles for 10 days. Not sure what is causing this + what treatment I should do.
