Do panic attack happens for one second, i sometimes feel terrible boom like feeling ? like something got squeezed inside me, can't really explain?

Yes: Panic attacks can range from butterflies In The stomach to debilitating fear and dread. Time frames also vary. The main thing is if you can function during one. If not seek help from counselors, your doc, or specialists who can assist in both discovering why you panic and how to treat this issue.

Neurology response: As noted above, a neurologist might consider an additional cause, such as an aura to a complex partial seizure, as brief panic for a split second, repetitively, can be experienced. Most likely, your spells are emotional, and would start treating this, BUT if things do not respond, would investigate further.
