I Have A Fracture On My Fourth Metatarsal. It Has

I have a fracture on my fourth metatarsal. It has been almost three months now. First x-ray showed nothing that the first doctor could see, but the second dr-a foot surgeon-was refer, said it was always visable, as a hairline fracture. It had started opening, but then started to heal some. I have nuropathy badly in my feet from Diabetes. He sent me home without doing anything. I am very frustrated. It seems like it is getting harder to put weight on it all the time. Any ideas?
