Hi, On June 14, I experienced sudden shaking of legs, pounding heart with high heart rate of around 110 followed by numbness which started from my toe to head and lightness in head. I also experienced slight chest pain. Out of uncontrollable fear, I assumed it to be heart related and immediately rushed to the hospital. There doctor did ECG, ECHO, and TMT along with thyroid test. All came back normal. But after few days those symptoms again appeared to which I had one more ECG which again came back normal. To this day, I had around 6 ECGs and all came normal. My doctor said that I experienced Panic Attack and prescribed me Anxiety tab - clonazepam along with Ciplar-40. From the last 2 Months I m on just one tab - Petril beta 10. And I must say Panic attacks have vanished but certain symptoms still come and go. Like a hard beating in middle of chest followed by a slight increase in heart rate which lasts for just 10 seconds, breathlessness. I wanna ask if this heart related or Anxiety?
