What Changes the Differential

Age modifiers

  • •Age changes baseline risk: pediatric, adult, and older patients have different top causes.

Severity and acuity

  • •Red-flag triage first: rule out urgent causes such as Ectopic Pregnancy.

Timing and pattern

  • •Timing matters: onset speed, duration, and recurrence pattern help separate benign from high-risk causes.

Associated symptoms

  • •Associated symptom clusters (e.g., Shoulder pain + Limited Range Of Motion, Shoulder pain + Stiffness, Shoulder pain + Hip Pain) materially alter the differential.

When Testing Is Needed

Immediate testing when red flags are present

  • •Vital signs and focused triage examination
  • •Pulse oximetry and ECG
  • •Basic blood panel (CBC, CRP, electrolytes, glucose)
  • •Immediate imaging based on dominant red flags

Group-directed workup

  • •ESR / CRP
  • •Autoimmune panel when indicated
  • •Joint imaging
  • •Creatine kinase for myositis pattern
  • •Focused neurologic exam
  • •CT/MRI when red flags are present
  • •Lumbar puncture when indicated
  • •Glucose and electrolytes
