Help: pharmacy, clinic, and staying calm

도와주세요 (please help me) is understood everywhere, instantly. For real emergencies: 112 is police, 119 is ambulance/fire. The 1330 hotline has interpreters in dozens of languages — save it before you need it.

Pharmacies (약국) handle most tourist ailments: 감기에 걸렸어요 (I caught a cold), 배가 아파요 (my stomach hurts), 두통이 있어요 (I have a headache). Point at the body part; 아파요 (it hurts) does the rest.

Stay calm, stay specific: 여기가 아파요 (it hurts HERE) while pointing beats a paragraph. Korean medical staff are used to international patients and will meet you halfway — your job is just the three words.
