I Have A History Of Panic Attacks But I Haven't

I have a history of panic attacks but I haven't had one in a few years. I started having sharp chest pains today around 11am. I've been monitoring them and the range from every 3-5 min. Its a sharp pain not a pressure type pain. I also have a rapid pulse and mild sob. The symptom check says collapsed lung, panic attack, and heart attack. I don't know how I would have gotten a collapsed lung, and my breathing doesn't seem that bad. I am a pretty healthy 29 yr old so I am doubtful of a heart attack. That leaves me with panic attack. But in the past the pains associated with my attacks were in the center of the chest near the sternum this is in the upper left quadrant, just above the breast.
I am wondering if I should consider heart attack a real possability due to the location of pain.
