What should I do if the results of B-ultrasound in two hospitals are different?

We should trust the big hospitals in the provincial capital. You can provide doctors with the results of B-ultrasound examination in local hospitals, so that doctors can examine this part more carefully. My wife has encountered a similar situation before, and she had a B-ultrasound in a small hospital. The symptom is that she can't afford menstruation. The doctor said that an operation was needed. Later, under the guidance of another doctor, the ovarian cyst disappeared after conservative treatment with antibiotic needles and B-ultrasound reexamination. In your mother's case, it may have been misdiagnosed in the local hospital.
