What causes buzzing/vibration feelings in the left side of my chest? I am not sure whether it is in my heart or breast area. I had it for two days when I was resting or trying to sleep. I had it another time awhile back. It did go away, but it is unsettling while it is happening.
I'm having this exact same thing. I was interested that you said it occurred when you are resting. That is when I notice it too...When I lie down, just at the point that I am starting to doze off, I will sometimes get this buzzing/vibrating sensation in my chest. Lasts for between 30-90 seconds then goes away. No change in heart rhythm noted during the event, though my pulse may increase slightly. The event itself is not unpleasant, but at the end I am left feeling rather jittery. I used to notice it only during the day when I wanted to take a nap, but lately it has also awakened me once or twice during the night. I mentioned it to my doctor and he just gave me a quizzical look. I am on blood pressure meds, and I have noted a possible association of these events with periods of slightly below normal blood pressure. I have also considered dehydration and a hormone imbalance as possible triggers. Wish I knew what it is.
