My dad had his gaulblatter removed and the doctor messed it up and my dad was the hospital for 2 months that $10000 what should we do
If the Dr did something wrong, or out of protocol you definitely have a law suit. If your father just had a hard time recovering from the surgery then the expense is up to him and the family to cover.
Consult with a lawyer and see if you have a case. It might be possible you have a medical mal-practice lawsuit here.
