Small mini rushes of adrenaline in chest all day. Anyone else?

Im a 33 year old male in good physical shape (exercise daily). The only way to describe what i'm feeling is little tiny rushes of adrenaline in the chest area that only lasts a second or two. You know the feeling if you got startled and you get that rush of adrenaline feeling in your chest or you get really nervous and feel it, it's like that just not as intense. Like mini ones all throughout the day, seemly for no reason and also when i'm even just slightly caught of guard. (phone vibrates, email dings, even the changing of a thought pattern to something else). Seems like anything will cause it and sometimes nothing at all. I've had this happen in the past and it usually goes away, it's just been happening longer this time (on the 2nd day of this). Also it sometimes happens when trying to fall asleep at night and it can keep me awake. This feeling of adrenaline rushes while i'm trying to sleep. My heart has seemly been pounding a tad harder than normal as well, just enough to make it noticeable and annoying. (again, I've had this feeling also but not for this long). I happened to read a somewhat similar story on a forum and someone mentioned it could be "Temporal Lobe Epilepsy", so that's got me freaked out a bit. I also get heart palpitations, something I've delt with for many many years. I do have health related anxiety for sure. Have had many many tests done in the past and it seems like a new "issue" pops up out of nowhere and I get freaked out about it. Countless different blood tests, Brain MRI, 30 day EKG holter monitor, Echo-cardiogram, Apnea sleep test, EMG of hands, arms, feet, legs, CT scans of abdomen and head, etc. Everything always comes back normal. Has anyone else experienced anything similar to this. Any recommendations?

Sure, I’ve had that happen more times than I can count. I’ve had anxiety since I was a child and I’m in my 50s now. I’ve always had adrenaline rushes in the fight or flight response for decades. You don’t have epilepsy. You have a hyper reactive nervous system due to anxiety. that’s why you feel the mini rush when your phone makes a sound or whatever.
When I am really uptight that happens to me. It’s nothing that’s going to hurt you however you can lessen the occurrences by bringing down your anxiety level. Long slow deep breathing helps and anything else that relaxes your mind. Think about what in your life is causing you anxiety and take steps to reduce it. Also, if you’re taking any caffeine in, that’s going to make it worse especially before bedtime. I can actually remember getting those rushes in kindergarten! It’s crazy. But the adrenaline does eventually wear off.
try to avoid reading things online because it’ll scare you for no reason. And then the adrenaline will increase and you will get those rushes. I find that the more I stay away from reading online, world events and anything similar that I feel way better and my anxiety level goes down. Do you things that you enjoy. and also don’t overreact when you get the rushes because it’ll produce more adrenaline. after having that happened to me for so many years, now I basically ignored it. I hope you feel better.
