How to say in English

If I have a headache during two days, and it's continuing, what can be possible variants of this phrase? For instance, "I have a headache for couple days". I mean, possible constructions in English!

1) I have had a headache for two days. (neutral tone)

2) The last couple of days I've had a headache.

3) I've had this headache for two days! (some emphasis)

4) I've had this damn headache for two days! (lots of emphasis)

5) This headache won't go away. I've had it for two days.

Hope it helps.
