Hey I'm confused at the moment as of what is wrong with me. I've just had a echocardiogram and my heart seems fine. I gave't yet had a test to check if anything is blocked in my heart and I'm awaiting the results of an ECG. It started about 2 months ago and I've had chest pains(my chest feels tight sometimes) and I've had a pain in a certain spot in what I can only describe is in my heart. I also feel my energy levels have decreased and sometimes feel down in the dumps which is definitely not me at all, usually bubley and always have someting to say....Any feedback would be much appreciated. I'm only 21,m. No family history of heart disease...and could it be linked to my lungs?
