While you are right, there is a common misconception that psychosomatic means that the patient is making up its symptoms and that it’s in his mind. That’s not what a doctor means by psychosomatic, but rather than the symptoms are totally real but that they are originating from stress.

So, any good doctor will try to heal your symptoms regardless of the cause. The only difference when they think it’s psychosomatic is that they’ll also try to treat your stress.
