Moment of Adrenaline out of nowhere

Hi everyone.. I have a question about an feeling of anxiety that I have been experiencing every day for the past month.  Ok, so the the day will be going fine, either at school or work or with friends, maybe a thought or two about some bad things for a couple minutes but that's it.  So, sometimes during the day for like a period of about an hour, I'll get this feeling of adrenaline running through my body, and I feel like I am scared for some reason.  My heart doesnt race or anything, its just an adrenaline rush feeling lasting for some time.  And, I am not thinking about death or any bad thoughts before it happens, It kind of just comes out of nowhere.  Can you tell me why this might happen, maybe I have too much time on my hands for that hour?  Please help?? Thanks.

Since this feeling began suddenly a month ago and is causing you some anxiety, I strongly suggest you see your doctor. It could be your thyroid, adrenal glands, or a number of other things, but it does need to be evaluated.
Too much adrenalin can cause fear because it is the "fight or flight" hormone that is released when we're facing danger. When it gets released when there is no danger, it can be very frightening. For those of us with anxiety or panic attacks, adrenalin is NOT our friend as it affects nearly every major system in our body.
I can pretty much promise you that this isn't happening because you sometimes have too much time on your hands.
See your doctor, who will run some blood tests and probably have an answer for you in a day or two. Be sure and mention the anxious feelings you get, but don't let that stop your doctor from running tests! Insist on the tests. Too many doctors will simply put your feelings down to anxiety, especially in women, and it may be years before we are accurately diagnosed.
I'm sure it's nothing serious. Let us know what you find out, OK?
Peace
