Everyone need make money to make a living.
It is possible all the text your doctor ordered was necessary.
The problem you have is you don't trust your doctor even you don't know how he works. Before you understand all you already claimed he's a HEI XING doctor. You put youself at the opposite of your doctor, whoes caring for you. That was wrong.
In United States, doctors on your side. Because they want you happy for their service, so you will go back to them. Only the insurance company has problems.
