Can't find the definition of ずっきり

Question

I haven't been able to find the definition of ずっきり in any dictionary.

A few examples:

• 今のほうがずっきりしてて好きです。(source)
• しかしどうもずっきりしない。 (source)
• ずっきり雨の日は腰が痛い、リュウマチか (source)
• 「何も御会計と御相談さ。」と、ずっきり言う。 (source)

It can seem to be a verb because it is sometimes attached with する, した, して, etc.

By the way, is ずつきり the typographical error of ずっきり?

Answer 1

• The first two ずっきり must be simple typo for すっきり (refreshing, clear, organized, etc). I haven't heard anyone say ずっきり for this purpose.
• The third ずっきり is a variant of ズキズキ or ズキリズキリ (mimetics for throbbing pain). See this.
• I'm not sure about the last ずっきり. Maybe it's a variant of ずけずけ (bluntly)? It must be very rare anyway... I think you can safely forget this example.

Answer 2

Judging also from the sentences you report, it seems to me probably just either a typo or a colloquial/dialectal way to say すっきり.

EDIT：　I actually read only the first two examples in your question and replied right away. I am not sure about the third and forth cases, could be something different.
