I need an opinion about panic attacks from someone who passed the ordeal and is ok now

So I've had a panic attack before (a big one that you feel yourself you are going to die for sure and your heart start beating non stop even without any effort taken). After that the Attacks were small, like you feel unease, some fear... (like in a period of months, rarely). But now I'm trying to get my emotions under control and I've been successful, thanks god, but still sometimes out of the blue I get that wierd sense of fear (the same one that happened before).Is it common to still have those sensations one in a while, even if you think you get things under control?
