I would definatly go seek a health care professional.
Hi anismushahera.
Because of the possibility of heart involvement , it's best to err on the side of caution, so I think you should get this evaluated at soon as possible.
It would be irresponsible for anyone to offer you any advice to the contrary,
even if in the end it turns out to be just a matter of some anxiety and shoulder pain.
Best wishes.
