ask another doctor, the first could be wrong XD

Depends.. We have the expression in USA that is: Its what my doctor ordered. Example: Yummy... yummy, it's delicious! it's what my doctor ordered When you desagree with someone about the food. You dont like the same food. Example: Michael says: Yummy... yummy, its delicious! its what my doctor ordered. Victor says: Ohh, you must get a second doctor's opinion. Or... Just look for another doctor.

再找个医生问问

Hi... You have to ask to another doctor his opinion to be sure the diagnostic is the same as the first one.
