give me your opinion on this matter?Its weird and it has bothered me for 3 years.I fgure it cant be heart? About three years ago I started waking up in middle of night and trying to catch my breath.I started having chest pains below my breast bone and around my heart.I went to doctor and he did gastrology test.Nothing.It continued around times that were stressful like arguing with co workers or other things.I went to hospital two times.They checked my xray and gall bladder nothing.Last year they checked my heart with stress test and the dye exam.Nothing!!!Well im relieved it isnt my heart but I cant figure it out.I have been on everything from nexium to prilosec.I just started taking blood pressure pills because it has gone up since this started.My symptoms include sweaty hands,heavy feeling around breast bone and chest, pain in lower back, light headed......could this be a panic attack.Ive seen 3 doctors so far and nothing.

Summarized question: What are the symptoms of a panic attack?
