Do I have a case, help please.?

For the past 2 years I have had swelling in my left great toe. I have been diagnosed with many different things being staff, Ostemyelitis, and chronic osteomyelitis. My current infectious disease is currently suing me for unpaid medical bills from 2 heart picc lines. And 6 exploratory surgeries. About a month ago the infectious disease doctor sent me to a surgeon for amputation. After amputation the surgeon had informed me that they sent the amputee to Washington DC to a lab for dissecting and examining. They found it was infact not osteomyelitis and it was simply a non cancerous tumor. So my question is, could I possibly counter sue for 2 years of wrong diagnostic, pain and suffering from 2 picc lines/6 surgeries. They did the amputation before even knowing the diagnostic, is that legal? Help please.
