Yes, you should speak with a medical malpractice attorney in your area as soon as you can.  You have what is referred to as a "failure to diagnose" case but they can be even more difficult to prove than "regular" medical malpractice cases.  Some states require that a docitor "certify" the case before you can even place it in to suit by stating that the actions were not standard in the industry or that they were against practiced principles - whatever the language requires.  You definitely have resulting damages from the failure to properly diagnose the problem and pain and suffering.  And you have future operations and pain and suffereing (damages). Good luck.
