🧠 Why Shoulder Pain Happens
The shoulder is one of the most mobile joints in the body, giving wide movement but making it prone to problems. Pain can come from:
- Tendons or muscles (especially the rotator cuff)
- Ligaments or bursa sacs
- Cartilage damage or arthritis
- Injuries like sprains, dislocations, or fractures
- Referred pain (from neck issues, or even heart or gallbladder problems)(Healthline)
🧠 Quick Symptom Clues
- Pain lifting arm overhead: often tendon/muscle issues.
- Pain at top of shoulder: AC joint or bursitis.
- Weakness or inability to lift: could signal rotator cuff or nerve involvement.
- Pain radiating down the arm or to neck: check for referred pain or nerve issues.(Healthline)
🆘 When to See a Doctor
See a healthcare provider if shoulder pain:
- Persists for more than a few weeks
- Causes significant weakness, numbness, or swelling
- Appears after a major injury or fall
- Comes with chest pain or shortness of breath (especially left shoulder pain)(Healthline)
