Ive been having a lot of anxiety lately and am a hypochondriac, for some reason Im focusing on my heart a lot now and this morning I lifted my arms up to stretch and got immediate sharp pain in my back, shoulder and chest that went away when I lowered my arms after a minute or two.  But since I have anxiety I panicked and my breathing got shallow and its been on my mind all day that I could have a heart problem or even some kind of heart attack.  I feel good now, should I still worry about this morning or was that something my anxiety blew out of proportion?
Hello, Your symptoms are not indicative of any cardiac disorders, including a heart attack. So, just relax and don't worry about it! A musculoskeletal pain seems to be the main cause of your complaints. For this reason, I would recommend taking a painkiller (acetaminophen or ibuprofen) for a couple of days and avoid straining physical activity. Hope I have answered your query. Let me know if I can assist you further.
