What can i do if a podiatrist misdiagnosed me and caused me harm?

I was misdiagnosed by a new podiatrist, confirmed by another podiatrist and an orthopedic surgeon. He diagnosed me with an neuroma and unspecified tendonitis I received shots from him on 3 occasions. My 2nd toe started curling up, and he told me I must have torn some cartilage that I don't remember. He taped my toe up and sent me on my way, I did not have an incident that tore my cartilage. When m third toe started curling up, I decided to see another Dr. The 2nd podiatrist diagnosed me with a 2nd metatarsal dislocation and something else with my big toe joint. The dislocations got worse creating hammer toes. NOT torn cartilage and a neuroma. I didn't have a neuroma at all. I had to have a difficult surgery after ruining my foot as a mailman based upon my initial diagnosis. I continued to walk 6-9 miles daily not knowing what was really wrong with my foot for an entire year. This surgery involved 6 screws and a plate which will put me out of work for 12 wks.MY feet are MY livelihood.
