Dear Cralaya,
I’m so sorry you are in this much discomfort. I do have good news, which is that by the description of your symptoms, this is VERY unlikely to be pain due to your heart. In other words, you are not having a heart attack. If the pain is worse with chest muscle movement, it is most likely musculoskeletal pain for whatever reason, either due to a muscle strain, trauma, or an infection. Typically ibuprofen can be all you need to make it improve.
However, there is also the possibility that it could be an infection of the sac around your heart called the pericardium; the infection is called pericarditis. I can’t completely tell by your symptoms what exactly this is. Your primary care doctor should be able to tell if it is pericarditis. If it is, it would be important to go to a cardiologist and make sure that you don’t have too much fluid around your heart, which can compress the heart and cause significant problems with the function of your heart. Another potential option is an infection of the heart itself, called myocarditis. This is a much less likely option, though. Finally, if the pain is as severe as you are saying, you may need to consider going to your local emergency department.
Thank you so much for your help. At my next Doctors appointment, which is tomorrow or the day after, I will make sure to bring up the infection of the pericardium, and make sure it is not anything serious. I will definitely try ibuprofen. I was very worried about it being a heart attack, and it was scary, so thanks for calming my nerves!. I think I will keep a log of how often it happens and how bad it is also to make it clearer for my doctor. Thanks SO much!
