Hi all, I haven't been feeling up to snuff lately. I've been having shaking sensations inside my chest area for a while, especially when I'm really tired. Three times during the last month, if laying on my side, I've been awakened by excruciating pain that surrounds my chest area. If I turn on my back and lie quietly for about 10 min or so, the pain eventually subsides. What a scary and painful thing to wake up to. My doc says she'd be surprised if it's related to my heart, but because of some risk factors, I will be having Stress testing done soon. Has anyone experienced anything like this before? Thanks in advance.
