I checked my heart rate about a half an hour ago, and I had about 70 beats per minute, which is normal for me. I've been coughing a lot, and I'm still freaking out about whether it's just some sort of esophageal spasm or an aortic/thoratic aneurysm. I really hate to double post like this, but I wanted to update. If anyone knows anything please respond! I'm really getting scared.
