I'm pretty sure a lot of you are in the same boat as me when I post about this. I'm an otherwise healthy 24-year old female that exercises regularly, and my family does not have a huge background of heart-related illnesses or disease. My parents are healthy, as well as my grandmother, and my cousins. Right now, I feel like I have shortness of breath. I feel like it is hard to do deep breathing exercises because I don't feel like I'm inhaling enough. I have chest discomfort that I can't seem to localize as well as chronic back pain. The back pain is separate due to the fact that I work in an office Monday through Friday 40 hours a week and sit at my desk for 8 hours straight, almost. I've had back pain for a while so that is not my concern. My left arm has also been aching, specifically, from my elbow down towards my hand (wrist, palm, fingers. I also have a slight tingling every so often). These symptoms have been on-going since Thursday evening. I have done nothing but try to do deep breathing exercises that help, sometimes, jumping jacks, and have been constantly looking up my symptoms online just to scare myself more (not on purpose of course). Any help would be appreciated especially any medications I should consider taking to ease my anxiety, panic, worry. I have heard that Benadryl helps. I am thinking of purchasing that today.
