English says my head hurts: the head does the hurting. Finnish turns it round, with two little verbs that never change for the person:

Sattua — to hurt — and the pain goes into the body part (the illative you met in Unit 6):

• Päähän sattuu. — My head hurts.
• Kurkkuun sattuu. — My throat hurts.
• Vatsaan sattuu. — My stomach hurts.
• Mihin sattuu? — Where does it hurt?

Särkeä — to ache — and the body part takes the partitive:

• Päätä särkee. — My head aches.
• Selkää särkee. — My back aches.
• Minua särkee. — I'm aching all over.

To make it clearly yours, add -ni: Vatsaani sattuu. — My stomach hurts. But Finns usually leave it out: whose head would it be?
