Hi I am 32 years old and 5 years ago I was taken off a benzodiazapene cold turkey by an unexperienced doctor.I went into what is called, protracted benzo withdrawal syndrome.I am very sensitive to ALL types of medications now.Six months ago I took an Antibiotic named flagyl and reacted very badly, almost as bad as when I c/t xanax. I feel like I am going through w/d all over again. I later found out that this particular a/b reacts very bad for people with benzo history.I am now experiencing heart pains. I feel like my heart is sore and it aches and hurts. It mainly happens at night and more when I am truly exhausted. I am concerned that because of my history of benzodiazapene use, unhealthy dieting etc.....it may be my heart. I have had bloodwork, chest x-ray, CT Scan, echocardiogram and they all come back normal. What can be causing this heart pain that radiates to my left arm neck artery. My throat feels weird too. It mainly happens at night???
