I Fractured My Leg And Had The Muscle On The

I fractured my leg and had the muscle on the front of my leg severed completely 5 weeks ago. Tonight I am having pins and needles in my foot and heel. Am supposed to be not weight bearing but have been using it a bit lately. Do you think this is why it's tingling? I also forgot to take my blood thinking injection for two days but just did it. Just don't want my leg to stop working or something!
