Help? How do I make it better?

For almost 4 days now I have a near constant sharp pain right around my shoulder blade. It hurts so bad all of the time and I dont know why or how to fix it. It's kind of like a pulsing pain. It hurts really bad for about 10 seconds, goes away, and then comes back. I kinda feel like it's a pinched nerve, but idk what that feels like exactly.

Ive try taking ibuprofen, a hot bath, and just having a heating pad it for a half hour. It's gotten to the point of where I want to ask my boyfriend for a half or whole muscle relaxer (he gets prescribed them). I hate taking medication, but I just want it to stop hurting. It doesn't keep me from doing things, it's just near constant pain
