Hey everyone! 
As NEET PG/FMGE/INICET aspirants, we’ve all stumbled over similar-sounding clinical signs during revision. So here’s a quick cheat sheet that helped me avoid mix-ups – hope it helps you too!
1. Murphy’s Sign 
→ Acute cholecystitis
Mnemonic: “Murphy’s Gall” = Murphy for Gallbladder
Pain on inspiration with palpation of RUQ
2. McBurney’s Point 
→ Acute appendicitis
1/3 from ASIS to umbilicus
Think: “McBurney burns with appendicitis”
3. Cullen’s vs Grey-Turner’s Sign
Both = retroperitoneal hemorrhage/pancreatitis
Cullen’s: Periumbilical ecchymosis
Grey-Turner’s: Flank ecchymosis
Mnemonic: “Cullen = Center, Turner = Torso side”
4. Brudzinski vs Kernig Sign 
Both = meningeal irritation
Brudzinski = Neck flex → Hips & knees flex
Kernig = Leg extension pain
Trick: “Brudzinski = Brain (neck), Kernig = Knees”
5. Trousseau vs Chvostek Sign 
Both = hypocalcemia
Trousseau: Carpopedal spasm with BP cuff
Chvostek: Facial twitch with tapping
Memory hack: Trousseau = Tourniquet (BP cuff)
