I live in a small town. My doctor told my sister that he suspected I had a specific medical condition. I have substantial damages if I can prove there was a breach. Obviously, these breach(es) didn't happen in my presence, though my sister recently told me about them. Is hearsay enough to make a (malpractice) case against the doctor? My sister gave me emails she sent to others divulging this diagnosis but doesn't explicitly say the source. Plus the "diagnosis" was never made because it wasn't accurate and turned out to be something pretty different and less prejudicial. I also have emails my sister sent to the doctor asking for referrals/info for doctors to help my "condition" (not specified) and the doctor was always vague in his responses & followed up via phone. Can I prove the breach?
