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.

Ice is for swelling; heat for pain of sore tissues. Hot water foot baths, preferably.
There's no way for anyone to know if you did anything to your original fracture. It should have bonded back together by now, but anything is possible.

My GUESS is that your calf and toes are so out of shape from lack of use that they are tight and sore. My GUESS is that sharp pains are from small nerves that are irritated from scar tissue and some tiny amount of swelling still. It doesn't take much to irritate a nerve, especially in the foot.

So.. massage while warm such as in a tub or big pot of hot water. Gentle rotation of the foot in all directions. Do that in bed and sitting, and any time you can. I suppose you could get another x-ray if it just doesn't get better. Many of us live with life long awareness of an old fracture because of the way it heals imperfectly or forms scar tissue internally.
