Pain is pretty general. Is it a knot? Is it burning pain? Is it sharp pain?
Is it deep? Does it correlate with movement? Where is it. Shoulder blade can be a 16" diameter area.
I had a knot just below my right shoulder blade for 5 months, almost debilitating me. Cure was the first day of surfing, pushing thru head high waves, and it hasn't come back now in 15 years.
