What could be causing severe pain under the right shoulder blade?

Answer:

If it is muscle pain, I would expect you to have severe pain with moving your shoulder through a full range of motion... Pulling/pushing would also cause a lot of pain in that area.

If you get the pain when you take a deep breath, then I would think more along the lines of pleuracy, a condition usually caused by a virus.

With either of the above, I would certainly urge you to see a physician, PA, or NP...
