[Grammar] Can you use the adverb "right now" with present perfect?

[popri]

I need native speakers' help.
I think "right now" is used in either present progressive or imperative form, but somebody said that it can be used with present perfect. I can't think of any sentences in which the adverb is used with present perfect.

1) If there is any, would you please give me some examples?

I don't count the following sentence as present perfect, by the way.
ex) I've got headache right now.

2) Are next sentences correct?
a) I've arrived right now.
b) I've come back right now.

Thanks.

1. Technically it's the present perfect, but it means the same as "I have a headache." "Right now" is correct there.
2. You need "just now" instead of "right now".

"just now" would sound more natural with the past tense, wouldn't it?

I arrived just now.
I came back just now.

 

[Raymott]

Yes, it would. But considering the OP is giving sentences in the present perfect, "just now" does work for them, but "right now" doesn't. Also, "just now" is OK (and more natural, as you say) with the simple past, whereas "right now" doesn't work there either.

"Right now" works with the present progressive and the future. "I'm doing it right now. I'll do it right now."

Thank you for answering, Raymott and tzfujimino. I feel so happy now and I can tell this to my English teacher who's a native speaker of Japanese.
