What causes sharp pain in both shoulders?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Sharp pain in both shoulders may be a sign of neuralgic amyotrophy, a nerve disorder that causes sudden, severe shoulder pain followed by muscle weakness. This condition affects the brachial plexus—a network of nerves controlling the shoulders and arms—and often begins abruptly, sometimes after an illness, injury, or vaccination. While neuralgic amyotrophy is one possible cause, sharp bilateral shoulder pain can also stem from rotator cuff issues, arthritis, pinched nerves, or referred pain from other organs.

Because the causes vary widely and some require prompt care, it's important to identify what's driving your symptoms. Take a free, instant, online symptom check to get personalized insights based on your specific symptoms and clearer guidance on your next steps.
