Hi! last night whilst I was sitting watching tv, I got a tiny chest flutter (best way that I can describe it) there was no pain just a flutter. About a minute later I got really sore pain in my left arm, it was on the inside about 2 inches above my elbow! I'm so terrified that it is heart related, I'm freaking out. The whole thing lasted around 15 minutes. This has happened one time before, about 2 months ago. Exact same thing.. I went to the hospital, they did 2 ECGS, a chest x-Ray and blood tests. They tested my blood straight away and then again 6 hour after. They said all was fine and that it ruled out heart issues. I know that I should trust the doctors but I just can't accept this isn't to do with my heart! Has anyone else ever felt this before?
