Hello,
The symptoms you describe are consistent with a musculoskeletal cause for your
chest pain. This kind of pain and sometimes last for just a few seconds and is associated with muscle spasms.
If the pain comes on with activity, especially with your left arm, this would also support this cause.
The chest pain that you are having is not consistent with anything related to your heart, since pain coming from your heart would almost always last minutes rather than seconds.
Any cause coming from the lungs would also last more than just a few seconds.
I would suggest trying to rest as much as you can, and taking
Tylenol or
Ibuprofen for the pain.
Usually this kind of pain will resolve over a week or two, if it lasts longer than that I would suggest seeing a doctor to get an examination to make sure this is the right diagnosis.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Aaron Branch, General & Family Physician
