I recently had my gallbladder removed because I was having a fallbladder attack. When the operation was done, the pain in my right shoulder blade immediately disappeared along with pain in mt chest and on the left fsde of my stomach. I am sure it could be something else as well. Hope this helps.
A crack in the shoulder blade can be caused by a hard knock during sports or a fall. Car accidents can also lead to the cracks. They can be healed if surgery is done.

you might have strained a muscle, in which case you're fine. but if it doesn't go away in about an hour or so, you may have a pinched nerve, in which case you should get treatment or apply warmth to your shoulder blade for several hours or as much as possible until it no longer hurts when you use your arm.
