After going through your history I am of the opinion that the you are taking a good combination of drugs for control of your blood pressure levels.
Side effects :
Amlopres :Headache, swelling of legs, fatigue
, sleep disturbance, nausea
, abdominal pain
H : Dizziness, allergic reactions, gout
But do not worry about these side effects as these are very rare, and even if you go for any other drug thinking of these side effects that new drug will have its own side effects. And its been 3 weeks you are receiving these drugs that means the probability that you developing any side effect with this combination is comparatively very less. So, the combination of drugs you are receiving is good and continue the same and follow your doctors advice.
Wish you good health
