Lately I've been experiencing some awful symptoms that feel heart-related. I've had chest pain, lightheadedness, heart palpitations, difficulty swallowing, and nausea. They come in episodes and are horrific. The Xanax I take on a PRN basis for panic attacks doesn't touch it, even when I double the dose. However, since I have the diagnosis of panic attacks I run into the unfortunate circumstance in which each medical provider automatically assumes that my symptoms are panic related. This stuff is real and I believe the physical stuff makes me anxious. I just want to be taken seriously. The doctor stated 2 weeks ago that she was ordering several tests to be done, but I've never heard back and have left several voicemails. Tomorrow I'm driving to the office to get to the bottom of it. But, I'm concerned that they just think me to be an anxious person and it will only further that. Has anyone experienced this? I'm feeling really depressed and sluggish now. I'm exhausted.
