Does this occur when you move a certain way?
Any other symptoms? Thanks
It may be nerve related and you may just get in the right position for this to occur. Inflammation of a muscle could also compress a nerve just for a moment and give the same symptoms.
However as you also know too, this could also indicate possible heart attack or stroke even.
Click here for symptoms of a heart attack and click here for symptoms of stroke. If you get any of the other symptoms listed on those sites above, then do get to the ER right away (even if just to be checked out)
Otherwise, I would suggest following up with your doctor, so you can be seen in person. You can also try a moist heating pad on the shoulder, just in case this is muscle related, as this can help loosen anything up. If you the pain doesn't subside and stays constant of if you start to have a problem with breathing, do be seen in the ER too.
