I Fell Off A Motorbike 2 Weeks Ago And It

i fell off a motorbike 2 weeks ago and it landed on my left foot. i wasnt doing any great speed, just slow and was doing an emergency stop on my cbt. at the time i felt i had just bruised my big toe and possibly my ankle but i continued with the training. its been aching more as time has gone by and after walking quite a lot the last couple of days i am now in much more pain. ive got slight pins and needles and its very sore when flexed in certain directions. the pain is in the 5th metatarsal region
