Hey guys, ive been dealing with alot right now, im Just really sad because im feeling this way again and all I seem to be trying to do is to look for reassurance ao that I can put this behind and try to be happy again...so for about a week now, ive Been experiencing tightness in the middle of my chest, right in my sternum, I don't have any pain or whatever...just like this pressure feeling, and I can't help but think it is heart related...I'm a 22 yo female with no history in my family of heart issues...and I think I would be feeling dizzy or out of breath if it was something serious...but I do feel palpitations sometimes so I Just can't stop but worry about my heart...can someone help me please? Has anyone been through this before?
