To say what's wrong with you at the moment, Brazilians use estar com + a noun — literally to be with:

Portuguese	English
Estou com febre.	I've got a temperature. (a febre — fever)
Estou com tosse.	I've got a cough. (a tosse)
Estou com gripe.	I've got flu. (a gripe)
Estou com dor de cabeça.	I've got a headache. (a dor — pain)

Two common complaints also come as adjectives, which agree with the person:

• resfriado / resfriada — Estou resfriada. — I've got a cold. (o resfriado — a cold)
• gripado / gripada — Ele está gripado. — He's got flu.

You'll also hear ter: Tenho febre. Tenho dor de cabeça. For how you are right now, though, estar com is the everyday choice.
