Fractured Calcaneus Bone, Pressure Bearing, On Crutches, Throbbing Sensation. How Will I Get Better?

Hi, I fractured my calcanius (heel) bone over 3 months ago. I was no weight bearing on crutches for over two months. I have been pressure bearing for the past month. In a walking but for 1 1/2 weeks and then switched to a tennis shoe. As of this last week I have been trying to walk with a cane instead of the crutches. However, I recently, 3 days ago; fell down while walking and I believe i just bent my toes back some. It does not feel as if anything is broke in my opinion. Nothing has swelled. Yet, my toes and the ball of my foot have been throbbing. If i bend my toes or curl them in a certain way, particularly when I am trying to walk it sends pain shooting up my foot. Yet my foot in normal position I can put full weight on it and it does not hurt. In addition to that the tendon right behind my ankle has begun to feel pulled and hurts tremendously as well. I do not know what I should do. I have tried both ice and heat and neither seem very effective.
