For the past few months I have been under severe stress due to multiple changes in my personal life. It often feels like my heart is going to pound out of my chest or maybe have a heart attack. I was diagnosed with anxiety, and prescribed Xanax l tab po tid. I cut them in half and always start with only half a tab first. So most recently I lost my marketing position due to territory cutbacks after marketing diligently in 19 degree weather....anyway following my termination I then came down with severe bronchitis. Started on Levoquin 1 po qd x 10 days, Tussinex syrup for my hacking uncontrollable cough, and Tessalon peerles (sp?), and Tylenol prn fever. Ok, I have had my 3rd dose of Levoquin, took the Tessalon....and my heart started pounding again...so I stopped them immediately. So now I am up today for the first time since 2/13 and I get a glance of myself and whoa! my lips r turning dark blue! Has never happened before. Again my heart is pounding so I took half a Xanax 0.5 and I am in bed now. I'm hoping to wake up again. Perhaps I am having some cardio problems? My normal B/P is 100/72, 90/60, always-that's one thing that is good. I am just not understanding the increased heart rate-when I saw the doc on Monday my pulse was 98???
