Meaning of said, wiggly

Hi everyone
I’d like to ask a few questions about the following passage:

She still remembered the sheer panic when she was a teenager over a patch of skin turning green, only to discover that it was simply a gold allergy, a reaction to a piece of jewelry given her by her boyfriend. [color=blue]Said boyfriend broke up with her a week later, her panic attack having gotten him all [color=blue]wiggly.

Does ‘said’ mean ‘mentioned’?
What’s the meaning of ‘wiggly’?

Yes, “said” in this context means “previously mentioned boyfriend” or “that same boyfriend.” Wiggly means upset, nervous, or “squirmy”.

Thank you very much, tagarbo.
