두통

This means 'head'. You might hear '머리가 아프다' (my head hurts), which is a common way to express head pain, but '두통' is the specific noun for a headache.

This is the verb 'to hurt' or 'to be sick'. It's used to describe pain in general, but '두통' is a specific type of pain.

This is a general term for 'pain'. '두통' is a specific kind of pain, a headache.

Many English speakers confuse '두통' (headache) with other types of pain. They might use it generally when referring to any ache in the head area, even if it's not a headache in the strict sense.

'두통' specifically means a headache. It's not a catch-all term for head pain. If you have pain from hitting your head, it's not '두통'.

저는 두통이 있어요. (I have a headache.)

This phrase literally translates to 'head hurts'. It's often confused with '두통' because both relate to head pain.

'머리 아프다' is a more general phrase that can mean 'my head hurts' due to various reasons, including a headache, but also fatigue or stress. '두통' is a specific medical condition.

머리 아파서 집중이 안 돼요. (My head hurts, so I can't concentrate.)

This term sounds similar to '두통' and both are related to headaches, but they are not interchangeable.

'편두통' specifically means 'migraine', which is a severe type of headache often accompanied by other symptoms. '두통' is a general headache.

저는 편두통이 심해서 자주 쉬어야 해요. (I have severe migraines, so I often have to rest.)

While not directly head pain, '치통' (toothache) can sometimes be vaguely grouped with '두통' by beginners because both are pains in the head region.

'치통' is pain in the tooth or teeth. '두통' is pain in the head.

밤에 치통 때문에 잠을 못 잤어요. (I couldn't sleep because of a toothache last night.)

This is a much more serious condition but sometimes the initial symptom of a concussion can be a headache, leading to confusion with '두통'.

'뇌진탕' is a concussion, a brain injury. While a headache can be a symptom, it's a much broader and more severe condition than just a '두통'.

운동 중에 뇌진탕을 당했어요. (I got a concussion during exercise.)
