Hello
As you mentioned that you were taking atenolol for 10 years .
After lisinopril , now you are taking
amlodipine i.e. ACE inhibitors and your blood pressure is under control .
Since you are also having
shortness of breath particularly when upstairs and also feel
throbbing pain.
No doubt the fatigue and edema are side effects of amlodipine ,but we should not forget other things.
As are a chronic hypertensive patient ,so I recommend you please
consult a CARDIOLOGIST and get in complete heart check up like EKG , ECHO to rule out any hear involvement .
However sometimes there are so many other possibilities which produces shortness of breath as
bronchial asthma, anemia , even knee pain (when upstairs ).
So deal as mentioned above.
Good luck.
