I had A-Fib about 8 years ago and had an ablation which has stopped the symptoms. I have recently had sweating episodes in which I soak my clothes or bed About every couple hours. When I had the a-fib, my only symptom was the sweating, I never felt the fluttering as a symptom. The muscle in my neck in the back has been spasming also and some leg cramps. I have an appointment with my cardiologist on 7/25.
