I am 31 years old Male. I had similar problem in 2011 when I noticed a minor shock on my left side of chest, specially during early morning when I wake up and it got worst after few days. It felt exactly like I got electrocuted, initially for 2-3 second and later on got worst and started lasting for around 10 second and more.
Been to GP and had checked everything about my heart, couldn't find anything. then after period of 4 weeks from beginning it started fading out and eventually stopped. I felt so relived.
Now again in 2013 Feb, after about 14 Months I had same problem and started worrying again. Now I have no Idea why its happening but I read somewhere this will come back time and time again.
Fortunately this time I used the " Hot Water Bag ". I Put on the area where I was feeling the sensation, Initially for 2-3 days when I had Hot water Bag on and when I got electric shock, I felt bit better as I was feeling less stress because of the hot water. So I kept using it for twice a day and specially just before I go to the bed.
Within a week time, all my shock wave has gone
and I feel so much better.
I would Highly recommend everyone who have same problem to use Hot water Bag for few days and I am sure you will see the difference.
I don't know the reason why this happen at first place but I found no solution through any doctors, and this was very stressful experience for me. But I found very unusual solution that worked for me and I really hope this will help everyone who has problem.
I know how it felt, so helpless when this happen.
