Hi I am a 20 year old female and will be turning 21 in just a couple of months. I have for the last probably 3 years of my life had pain in my chest on more towards the center/left side. This is shooting pain that will shot up towards my left collar bone as well. At times it prevents me from being able to take deep breaths , though I feel that is the only way to get rid of it. What brought me here today, however, is that fact that while sitting at my desk at work, with the blinds open, a bird flew right up to my window. When it did I was startled to say the least and directly after the shock/scare the pain started happening again. I m almost 100% positive that as a very small child I was diagnosed with a slight heart murmur (spelling) but I ve always been told since I hit about 8-9 and on that I grew out of it ... What in the world could this be? It really does scare me!
