Hi, my name is Toni. It was last year when I was in Portugal for 2 and half weeks, and when I was about to board a plane back to Canada I had the following symptoms... flushed skin only on face, heart elevated to approximately 120 b/m, extreme fatigue, moderate diarrhea, and loss of appetite. So, I was rushed to emergency, and they ordered an ECG, but found nothing irregular. They also did urine tests along with blood work, but again nothing seemed wrong. Since, they didn t find any wrong they prescribed me bisoprolol due to the increased heart rate. They kept me there for around day to make sure everything was fine. I then flew back to Canada. For the first 6 months, every month I would experience usually 1-2 episodes , and these were the same symptoms I had already experienced. Over those 6 months, I visited a few doctors and specialists, but no one seemed to know what was wrong. The next 6 months, I experienced none of the symptoms and appeared normal. But, this week I ve had 4 episodes. Any ideas? Thanks, Toni
