I am a 31 year old male, 5 11 185 lbs that has been in relatively good shape over the years with no prior conditions/surgeries, etc. But I have something that has been bothering me for the last several weeks that I believe to related to stress but I m not sure. Usually occurs 2-3 times a week recently. At the end of the work day or sometimes during the day the bottom of my chest area which I am pretty sure is the Xiphoid Process area has an unusual tightness. Literally the middle of my torso. It usually will take 1-2 hours after work when at home for it to subside. Then when I press on that hole location at the bottom of the sternum and just above that on the bone itself it is tender and tight, which causes some trouble breathing and hyperventilating. In the past, I ve suffered from panic attacks but this is something different. Again, I believe it to be related to stress as I have an anxious feeling when it occurs and I definitely am going through a lot more stress than I ever have with work, personal life, etc all at the same time. Also, I ve been sitting down a lot more at work and I m not sure if it s because I ve been slouching forward too much. Also not sure if it relates to how I sleep on my back as some mornings when I wake up, the middle of my back and sometimes that area in front is a little sore. Is there something I should get checked out? Or if it is something minor, possibly some breathing techniques, etc that can help when I get these feelings?
