In the middle of last night I got a stabbing

Patient: In the middle of last night I got a stabbing pain in the bottom of my right shoulder blade. It hurts when I walk, take a deep breath, or even just move my body in any way. Is this just a pulled muscle or something more? Because the pain started at 10 at night after I had been to a hottub and had been relaxing

Symptoms: Pain on the right side of the torso

Doctor:
