Sometimes if I m lying down on my bed sideways (heart closest to the bed), my heart area gets a sharp pain if I inhale, as if it got poked with something. Exhaling is fine, so I can only take small breaths. It goes away if I massage the area. Is this a symptom of something serious? Should I have this checked out? Thanks for all the replies, but this has been happening for years, and only occurs maybe... once a month at most. I don t smoke, do not feel anything weird afterwards or before, just some pain. I occasionally play sports and do not feel any abnormalities if I get hit around my heart area. Mostly occurs during sleep, and after a few massages, I m good and I go straight back to sleep, or wake up if its already morning. I m kind of reluctant to go get this checked out because it doesn t happen often. Guess I ll tell my doctor in a couple of weeks when I go for my semi-anual checkup.
