My leg needs your help

I initially crushed this leg on a job in 2006 and some time back a dog bit it which set off a strange sequence of events which almost killed me
The hospital saved me but found it a mystery said that it took on a life of it's own and were unable to diagnose the true problem that was eight doctors ago
But the medication they gave me worked for some time even though but at this point it seems to have run it's course
So now I have to have find another solution which means different doctors and different mediations and to survive during the process. which at this point I can't afford to do any .
I'm not giving up this leg with out a fight but unfortunately I need some help from others to do it
