While I don’t have the stomach pain, I do have a panic reaction to adrenaline. It’s frustrating. Doctors don’t have answers so they are quick to push sedatives. I’m exploring the connection between adrenaline and blood sugar as a clue to the anxiety response. People will be quick to label this anxiety and, in my 53 years experience with this phenomenon, it’s not that simple. I believe there are physiological factors at play, too.
You have no idea if your body is releasing adrenaline, right? You aren't measuring it. You're just assuming your body is releasing more than usual, but it actually might not be doing that at all. The pain sounds like something akin to what we call butterflies some folks get when they get nervous. You also would only know if you were having heart palps if you have been measured and diagnosed with that. A lot of things feel like heart palps, but most aren't. Anxious people have these kinds of sensations a lot. Unless you've seen a medical professional and been diagnosed with a heart problem or an adrenal gland problem, you have no idea if you have those things. What you do seem to have is an anxiety problem, and you deal with that first by seeing a psychologist who specializes in the treatment of anxiety. If you get panic attacks, you're going to experience a lot of physical sensations along with it. But the problem is the thoughts that cause the anxiety, again assuming there isn't an underlying physiological cause such as nutritional deficiencies, thyroid problems, blood sugar problems, etc. And the brain and the nervous system are pretty much the same thing, as the brain controls most everything one way or the other. So it's possible there's an underlying physiological cause, and it never hurts to get tested for all the things known to cause anxiety, but for most of us anxiety sufferers it's a mental issue in the way we think. Therapists are your first stop in trying to deal with this.
