So for a few years now I've been occasionally experiencing what I found out recently to be heart palputations. I've had an echo done and everything was fine they said. My doctor also said it was due to PMSing, but I experience it all month long, and it worsens with PMSing. Every time I have an "episode," it leaves me exhausted for days, which is terrible because it happens every few days. Basically, I'm tired all the time and I feel my heartbeat, which is irregular, all throughout my body. Nothing I do seems to help slow my heart down, and it gets worse when I try to sleep. I lost some weight when I was 16, and it became rare that I'd have this problem and I wouldn't get tired back then. I recently turned 18 and the episodes have been a lot more frequent and extreme in the past few months. Any ideas?
