question: Hi I have been having sharp electric shock like pain shoot down the left side of my chest. It s extremely unnerving and uncomfortable. I feel it slight down my back at the same time and it last for all of 2 seconds, when it stops I m left with a pins a needles sensation and i feel like in going to have an anxiety attack with the fright it gives me. I am a very stressed person I am 24 years old with a heart murmur I ve had an ECG and an ECCO of the heart test and all came back fine apart from an irregular heart beat but I was told not to worry that was normal with the heart murmur. I was reading up on it online and I think it could an inflamed nerve, do you think this is possible? Or what should I do? It s been going on for weeks now and I think all the worrying will cause a bigger issue for me if I don t get some reassurance. Thanks.
