High Pulse Rate While Waking Up, Cannot Eat, Worsening Acid Reflux. Taking Bactrim, Nose Still Clogged. Should I Worry ?

Had a EKG done last week which appeared normal i guess because they released me without a second thought, im 20 years old male high blood pressure and lately my pulse when i get up during the day is at a constant 116 or in that general area which i was told is very high... and im worrying now because its starting to make me dizzy and i cant eat my acid reflux is getting to be horrible, my nose is clogged has bactrim i think it was, the antibiotic it did nothing for my nose and sinuses just gave me worse acid and bad pain, so i stopped it and even before i stopped it my heart rate was in the 116 area and after i havent taken it in 2 days its still in the 116 area, should i be worried about this? i keep telling myself that the EKG was normal so nothing could be wrong but its scaring me my pulse rising that high and me feeling very dizzy and like im going to vomit all the time.
