Sharp pain intermittently beside right shoulder blade?

If pain is exacerbated with arm and shoulder movement, muscle strain or spasm is likely the cause. If pain is increased with cough, deep breathing or sneeze, radiculopathy due to poor posture during sleep or after lifting a heavy object. If pain seems not changed with body position but lancinating or shooting to the front, shingles can be the culprit so watch the area for rash next 1-2 days.
