Update:
I took my newest x-ray this morning.
The Precice is not "precice", by the machine I have lengthened 57.26mm. But the gap of my bones is 6.2xcm (the gap was less than 2mm after surgery), and the nails in my x-ray lengthened 6-6.1cm. So I decided stop lengthening from today.
Even I almost didn't work at all, but my nails bent still (and was at very early stage), but fortunately the bent degree didn't go much worse. Just a little.
My ankle cannot do much move, but it's since after surgery, not developed in lengthening time.
And the most annoy complication is my tendon adhesion, if I do less practice few days it's become worse, and even I do much practice everyday, it still cannot gone by soon.
Back to the first complication toes pain, it only happened for dozens days and it's gone totally even I didn't stop or slow down the lengthening, but I slow down the lengthening after I nearly reach 5cm.
