Yes, they have the choice to sit at home and complain about losing a good job over a very low risk injection.i agree with everything else until this part:
i am pretty sure that they know more about than average person does. and they see a lot more cases than any of us do. i respect their choice. and if patients do not trust them or their choices, they are welcome to opt out from being treated by someone they don't trust or go home and take chances with the issue on their own.
as nsaspook like to state - choose wisely
