According to data shared by the National Institute of Health, the estimated prevalence of shoulder pain ranges from 4% to 26%. Assuming this data is accurate, this means upwards of 1 out of 4 people are struggling with shoulder pain at any given time. Both acute and chronic shoulder pain can feel dull, achy, sharp, or throbbing. It may be associated with weakness, tenderness, swelling, bruising, and instability at the shoulder joint and make it difficult for a person to lift their arm. Sometimes, numbness, tingling, and weakness can also develop in the arm, hand, or finger.
