I also am sorry you still have to put up with this incompetence. I know it takes a lot of energy to respond to the incompetence, but if it were me, it would at least make me feel good to find the doc and yell at him. I am not a lawyer, and also not a litigatious person, I think doctors are sued too much, but in your situation, they should be sued. If you document everything, you can always talk to an attorney when you have more energy at a later date. Anyway, I hope things go more smoothly for you and your mom from this point on.
