Hi I'm A 58 Year Old Male Recently Started Treatment

Hi I'm a 58 year old male recently started treatment for high b.p. I'm taking loristan (sp?) And a diuretic. It's been two weeks on the loristan but only 5 days on the diuretic. I'm down to an average of about 124/85 but will get an occasional reading of 110 or even 106 but if I take it immediately after its back to the typical. I also have gerd and the last couple of days my belly has been hard and bloated which I find typical when it's acting up. My question is lately my heart rate has been 106- 110, can gerd or the meds cause this and should I be worried? I'm new to all this and frankly, a little freaked out. Thanks.
