Finally after about 4 months I am able to walk again. It all started half februari 2014, it is now first of juli.
On the Mri, taken about 2 months after the first complaint, it showed that my inner sesamoid did not light up and the orthopedist said it was 'defragmentating', it was dissolving and not healing. Also there were problems with the ligament between the sesamoids.
All that time I had a lot of pain, the foot was very swollen and cold, and i could not wear shoes. They tried to put the foot in a cast twice, but that did not work. I tried to use a Darco orthowedge shoe, but that put too much pressure on the area. My crutches were the best help. Except for doing the most necessary, I was immobile. Everytime I did something (groceries or some household work) with my crutches, I had a lot of pain, like someone hit me with a piece of wood under my foot, a sort of stiffening pain, and I would put my foot up again for hours. Also I was very afraid the bone would dissolve. All this time I went to a fysio. He treated me with ultrasound high frequency. This stimulated the bloodflow. But the area was so tight and sensitive that it was painful, I even stopped the treatment temporarily. Five weeks after the mri was taken my fysio encouraged me to try standing on the foot again. A week later, to take small steps. In this way I slowly started using my foot again. The foot was still thick but the area was starting to get pink again, from the edges out. According to my fysio I had some paintrauma (crps) which means that the nerves and tissue are still reacting on old trauma. So I had to work on desensitizing that area. And that worked, but very slowly. I started using the Darco shoe, so I could walk and put most pressure on the heel. I walked unnatural, because the darco shoe was higher, but because I got mobile again, the healing started to speed up. After all, I was using that limb again.
At the moment, now 5 months later, I am walking on my mountain shoes and barefoot at home. But if I walk too much, the whole foot gets thick. This is still a reaction and normal according to my orthopedist.
Advice I can give you: don't panic, this takes months, and even can get worse when you think it can't. Also: go to a good fysio, who can stimulate and support you (also mentally). Don't force healing, your body has it's own pace. Search the balance between loading and unloading constantly, this is a very fine line.
My fysio talked about the piezo electrical effect: by putting light pressure on the area, it gets a certain stimulation to heal. I think that is also what you try to achieve using a bone stimulator (which I also borrowed from the hospital). This is low frequency ultrasound.
