I have checked the leaflet with my amlodipine.
This lists some side effects where you should contact your doctor immediately, but your symptoms aren't mentioned.
There is then a list of very common side effects (more than one in ten people)
It says if any of these cause you problems or if they last for more than a week, you should contact your doctor.
Abdominal pain is on that list.
It is therefore right for you to contact the doctor, and he or she will probably change you to a different medication. I believe they have several options.
I agree with what others have said. If you want good service from the doctor, try to hold back on the aggressive and critical tone you have shown here. They are only human.
