Hi. I was unable to sleep most of the night last night. My heart seemed to be beating hard and quickly. I have been suffering from insomnia over the last week or two. When I did wake up this morning from a couple hours of sleep my heart felt like it was pounding out of my chest and my right arm was numb and tingling, then it moved to both arms. I feel extremely weak too. This is the second time this has happened to me in the last 6 months. I ate an egg and an apple hoping some protein and carbs would help. My arms are feeling somewhat better after 45 minutes but heart is still rapid and pounding. Heartbeat is around 100 beats per minute.
