When to see a doctor
  • Call 911 now: shoulder or arm pain with chest pain or tightness, breathlessness, sweating or feeling nauseous. It can be a heart attack.
  • The ER today: after an injury, a shoulder that looks out of place, or an arm you cannot move or lift.
  • Urgent care the same day: a hot, red, swollen shoulder, most of all with a fever or feeling unwell. It can be a joint infection.
  • Urgent care or your doctor today: sudden or very bad pain, pins and needles that do not go away, no feeling in the arm, or pain in both shoulders.
  • Urgent care or your doctor today: a lump, weight loss or pain at night with feeling unwell. Also several swollen joints, or morning stiffness in both shoulders and hips past 45 minutes.
  • A doctor within days: a pop in the chest or armpit on a heavy bench, then bruising or a changed chest shape.
  • Your doctor or a physical therapist: pain getting worse, or no better after 2 weeks of self-care, or a shoulder very hard to move.
  • A shoulder surgeon: a tear from an injury, soon. A tear no better after 3 to 6 months of proper exercise, or a shoulder that keeps dislocating.

I am not a doctor. This is not medical advice. This is self-education. Every dose on this page is the one a trial or a label used, quoted from it. It is not a prescription. Talk to a physician who has your history before any medicine or procedure. Chest pain with shoulder pain: call 911. An arm you cannot lift after an injury: the ER.
