Its my dad actually, the doctors did all kinds of tests on him and said he had a hernia. So they performed surgery on him and it turns out he didn't have a hernia, it was just some fluid. He is now complaining of the same symptoms he had before the surgery but it's worse, i think he has appendicitus. He has every symptom ot it, even if not they were wrong.
Could he sue for medical malpractice and how much money could he get?
